Flexible water line: technical characteristics. Types and characteristics of flexible water connections, features of operation and selection Flexible water connections technical characteristics

To connect water heating equipment, toilets, faucets and other plumbing devices, a liner is required that will connect them to the water supply. This element can have a flexible or rigid design.

Most users prefer the first option. This choice is not made without reason - the flexible connection for the mixer is compact, practical and easy to install. Are you planning to purchase and install such a device, but doubt your own abilities?

We will help you solve this problem. The article describes the features of different types of flexible hoses, indicates the specifics of their application and provides practical advice on choosing the appropriate option. In addition, we have prepared detailed instructions for installing the faucet connection.

Unlike, a liner equipped with a movable design can be easily installed in hard-to-reach places with limited space.

Main advantages of the products

During the labor-intensive installation process, steel pipes are bent and secured with clamps, resulting in a bulky metal structure. Installation of a flexible product is much simpler, while the overall quality and reliability of the entire system remains high.

The device is a durable elastic hose with a length of 0.3 to 5 meters. Fasteners with rubber sealing rings are inserted at the ends on both sides.

Flexible eyeliner is often used in interior design solutions. When connected to built-in faucets, it is hidden in a separate block located inside the wall

Typically, well-known faucet manufacturers equip their equipment with this type of connector, which is justified by a huge number of advantages.

Main advantages of the products:

convenient and safe operation;
sealed design made of high quality materials;
the installation/disassembly process is simple for an inexperienced user and does not require specific knowledge, skills and professional equipment;
resistance to vibrations and the effects of hydraulic shocks that periodically occur in the pipeline;
long period of serviceable service subject to correct operating conditions;
maintaining normal performance over a wide temperature range.

If necessary, flexible hoses move freely relative to the mixer and other plumbing fixtures, which cannot be said about their counterparts.

If you perform such manipulations carefully, you do not have to worry about accidental damage to the structure.

Reliable products with appropriate certificates and proper labeling are sold in specialized stores. The accompanying passport describes in detail all the characteristics. The declared service life should not be less than 5 years

Of course, the listed advantages apply only to high-quality products. To purchase a hose with good technical characteristics, you should pay attention to products from reliable brands.

For example, Tucai, Mateu, Uni-Fitt. These manufacturers provide a guarantee for their products and have sanitary permits for contact of devices with drinking water. Companies are popular among domestic manufacturers Monolith, Flexiline, Aquatechnics.

Negative aspects of the device

Elastic hoses, although they are the optimal way to supply water, are not without drawbacks.

Based on the results of the analysis of consumer reviews taken from thematic forums and social networks, the following negative nuances were highlighted:

products are afraid of excessive twisting, tension, kinks, which provoke irreversible deformation of the structure and greatly reduce the service life;
if there is an open fire source near the intended installation site, installation of a flexible hose is prohibited;
When water is simultaneously supplied to several rooms, vibrations occur in the bellows tubes, causing a characteristic hum.

The metal elements present in the device oxidize over time, which leads to the onset of corrosion processes.

When purchasing a product, you need to clarify which plumbing fixtures it will be used to connect to. The connection method depends on this. The sales consultant will show you the types of connections that are suitable for faucets

It should also be taken into account that certain types of flexible liners are sensitive to critical temperatures. Water that is too hot and close to boiling can damage the device, causing unwanted leaks and flooding.

Types of eyeliner: characteristics and specifics of application

Elastic hoses for faucets are divided into two categories: reinforced braided hoses and bellows tubes. Let's look at the features of each type of product in more detail.

Flexible hoses with reinforced braid

The first type of liner is a soft hose with high elastic properties, reinforced with a special braid.

The ends of the tube are equipped with fittings, with the help of which the structure is attached to the mixer: on one side there is a fitting, on the other there is a union nut with a certain diameter of the external thread. Reinforced devices have an affordable price, so they are most in demand among buyers.

Despite the simple production technology, the structure of the hoses is quite complex. The base consists of rubber, rubber or cross-linked polyethylene (PEX).

Experts say that in systems that supply drinking water, the use of rubber hoses is undesirable. The entire length of the product is braided with wire thread. Various materials are used to make braiding.

Stainless steel. The most common type of winding for reinforced hose. It is characterized by optimal operating parameters of the average level: the device functions perfectly within 10 atm. pressure and +95°C of the liquid passing through it. Stainless steel devices operate stably for up to 10 years.

Galvanized wire is a budget option both in terms of price and technical characteristics. Eyeliners made of this material have good flexibility, but they are not strong enough and quickly fail

Nylon. The material has improved performance characteristics. Eyeliners with nylon braid are maximally functional: they can withstand up to +110°C and up to 20 atm. pressure. Their service life significantly exceeds their analogues and is usually at least 15 years.

Aluminum braid suitable only for those systems where the water temperature does not exceed +80°C and the operating pressure does not exceed 5 atm. This material is susceptible to corrosion, so it is better to use it in rooms with low humidity. Flexible hoses reinforced with aluminum braid do not require replacement for about 5 years.

Bellows tubes for water

The second type of liner is represented by bellows hoses. The durability and reliability of these models is much higher than reinforced products. The devices are distinguished by their unusual design, which gives them excellent flexibility.

It consists of stainless steel assembled into alternating rings of different diameters. At the initial stages of production, the hose blank is selectively crimped, resulting in a movable corrugated shape.

The bellows liner for water supply can be foldable or have a fixed length. The first option stretches within the range established by the manufacturer: from 200 to 355 mm, from 140 to 250 mm, etc.

Care must be taken when handling collapsible hoses, as excessive stretching will shorten the service life. Fixed length eyeliner cannot be stretched. It is produced in a specifically designated size: from 20 to 80 cm (in increments of 10 cm).

The devices exhibit high resistance to low and high temperature parameters. They work great in the range from -50 to +250 degrees. The service life of bellows tubes reaches 25 years

Bellows hoses have a common disadvantage - noise when supplying water to several consumers at once. The problem is relevant when, for example, water is supplied to the boiler, toilet and faucet at the same time.

Basic criteria for product selection

A few simple recommendations will help you choose a faucet liner that is suitable in all respects and will last for years without any problems.

Before purchasing a product, experts advise:

Check the compliance of the actual operating temperature parameters, or with the technical characteristics of the liner specified on the label and in the manufacturer’s instructions.
Consider future operating conditions when selecting braiding material. For damp rooms with poor ventilation systems, you should not purchase products with metal braiding. Condensation that will settle on its surface will quickly lead to corrosion and damage the device.
Estimate the weight of the product. There is a high probability that the hoses are too light and are made of aluminum and low-grade metals that quickly deteriorate during operation.
Make sure there are no strong chemical odors. They indicate the use of hazardous technical rubber in the product.
Test the eyeliner for elasticity. Insufficiently flexible, “oak” tubes will quickly crack and burst a short time after installation.

One of the main components of a hose is the fittings. They must be examined carefully. It is important that they are well pressed and have no visible defects.

The pressure parameters in centralized water supply systems are about 4 atm, but they are characterized by frequent fluctuations. For safety reasons, you need to choose hoses with a margin of 20-25%

Optimal materials for nuts are nickel-plated brass and stainless steel. Aluminum is absolutely not suitable for water supply. Also, do not buy eyeliners with flimsy plastic fittings.

When choosing a device, they are guided by the type of connection to the water supply and mixer, the type/dimensions of the threaded connection, and the length of the hose.

The thread can be internal or external with dimensions ranging from 0.5 to 1.5 inches. This parameter is coordinated with the holes in the pipe and device to which the hose will be connected.

For sinks, shower stalls and sinks, it is better to consider liners with a diameter of at least 10 mm. The required length is determined based on the distance between the plumbing fixture and the pipe outlet.

It is considered ideal if, after connecting, no unnecessary stress is created on the hose and no additional bends are formed.

Reinforced and bellows products made from cheap components and low-grade raw materials are seriously limited in service life

Instructions for connecting the liner

It is not at all necessary to involve specialists to install flexible hoses. You can cope with this simple process on your own, spending a few minutes. The hose is installed not only for new, but also for already used faucets.

Replacing the device is extremely necessary in two cases:

the eyeliner is severely deformed or burst;
Leaks have appeared in the connection area with the mixer and pipeline due to wear or damage to the gasket and union nut.

The installation procedure for connecting bellows and reinforced liners is identical. The first thing you need to check is whether the integrity of the product and fittings has been damaged during transportation and storage.

You should then take precautions by completely turning off the hot and cold water valves in the water supply. To drain the remaining liquid, you need to open the tap.

For installation/disassembly you will need a wrench or an adjustable wrench, which is selected to match the diameter of the union nut. Using a wrench, remove the part of the old hose connected to the water supply. Water may spill out of it, so place containers under the fastening points in advance.

If you experience difficulty unscrewing, the connection area is most likely rusty. The resulting deposit can be easily removed by treating the surface with a solvent or technical lubricating aerosol WD-40

After disconnecting the hose from the water pipe, you need to remove the mixer by loosening the fixing nuts. Next, using the same key, you should disconnect the water supply from the mixer.

The new device is connected in the reverse order. At first, the nut is tightened by hand, then tightened with a wrench.

If the hose and faucet connectors do not mate, you can use additional adapters. The tightness of such connections is ensured by linen thread or FUM tape.

When installing the product, you should adhere to several rules:

straighten the hose before installation, avoiding kinks;
screw the flexible tube to the outlet and mixer without using excessive force;
perform fastening in such a way that it is easy to get to the installation site for the purpose of preventive inspection (recommended inspection frequency is once every 6-12 months);
connect pairs of parts made of similar materials to prevent the development of electrochemical corrosion; brass + copper is also suitable.

The final stage of installation includes mandatory testing of the connected structure. To check the tightness and capacity of the hose, the water supply is connected, after which the functionality of the device is assessed for half an hour.

If you find any collecting drops at the fastening points, you need to tighten the nuts again with a wrench. If everything is in order, then the hose is ready for full use.

Any line connected to the water supply is constantly subject to stress. Because of this, there is always a possibility that the flexible tube may burst, unable to withstand the stress in the system.

To avoid having to correct the serious consequences of flooding, it is advisable to turn off the water supply taps when leaving the house for a long time. A good solution is to use an “anti-flood” system

Convenient and practical flexible devices are stubbornly pushing their competitors in the form of rigid metal pipes into the background. They are easy to install, quickly replaced, and do not require special care.

However, you should not try to save money on such a purchase: products of dubious quality can entail significant financial losses in the future.

A flexible water supply will help you connect a faucet, toilet, water heater and other plumbing fixtures even in the most inconvenient location. It will allow you to abandon rigid pipes that require a large number of connections, and do without calling a specialist. Let's find out how to choose and connect a flexible plumbing hose correctly so as not to flood your neighbors later.

Types of flexible liner

For water, 2 types of eyeliner are used:

reinforced;
bellows

Reinforced

The first type of flexible hose is a soft elastic hose, reinforced with wire braid, with connecting elements at the ends (fittings). The tube has a complex structure, despite its simple appearance. It is made from synthetic EPDM rubber or PEX cross-linked polyethylene. It is braided with a thread of wire made of stainless steel or aluminum. The reinforced liner, which can withstand higher pressure, has a nylon braid.

The product is cut at the factory into pieces of the required length. At the ends, metal nipples with fittings or union nuts are inserted into it. Then the braid with the hose is compressed with a steel sleeve around the bushing. Connection to pipes is made through rubber seals.

Flexible water liner has different diameters: 1 and 1/2 inches, 3/4, 3/8.

Bellows

Bellows hoses are more reliable and durable. They are made in the form of alternating rings of different diameters made of stainless steel. During production, the workpiece is selectively crimped, after which it receives a corrugated shape that provides high flexibility. The cost of such a hose is much higher.

The eyeliner is available in two types:

with fixed length;
foldable.

The first does not stretch and has a certain size: 20, 30, 40, 50, 60, 70 and 80 cm. For the second, the range of minimum and maximum values is indicated: 140–250, 200–355 mm, etc. It is not recommended to get too carried away with stretching, since this affects the service life of the product.

The disadvantage of a bellows hose is the noise that occurs when water is simultaneously supplied to several consumers, for example, to a faucet, toilet and washing machine. To avoid this, it is recommended to purchase hoses with a plastic coating.

Technical indicators

The main parameters of a water supply system are pressure and temperature. Standard pressure values differ in different systems:

Centralized water supply - 4 atm.
Autonomous heating of a private house - 1.5–3 atm.
Central heating – 2–4 atm.

Bellows liner has higher performance, but it is important who the manufacturer is. Hoses from the AKVAPROF company are designed for operating pressures up to 16 atm and temperatures up to 150 °C, and the GIANT variety of the same type has increased throughput and can withstand temperatures of 250 °C.

How to choose a flexible eyeliner?

To choose the right hose, consider the following parameters.

The sleeve must be suitable for temperature and pressure. For example, a flexible connection to a toilet can be of any type, but only a hose for hot water will fit to a boiler.
The braiding material is selected based on operating conditions. In rooms with poor ventilation, where condensation may occur, it is better not to use a product with metal braiding.

The reliability of the eyeliner depends on its flexibility. You can check it by taking one end and placing the hose horizontally. If it bends slightly, then elasticity (and, accordingly, reliability) is low.

The fittings are selected without defects, the sleeves must be pressed around the entire perimeter. The material for making fittings is brass with nickel coating or stainless steel. Aluminum is used for gas, which is completely unsuitable for supplying water, since it quickly deteriorates in a humid environment.
Hoses for household water supply systems must be made of high-quality rubber without a characteristic chemical odor.

The hose for cold water is marked with a blue braided tape, for hot water - red. If the inserts have both colors, the product is universal. Cheap products do not have such markings.

The sleeve is equipped with union nuts or fittings of sufficient thickness and strength so that they do not crack when tightened. If the liner is too light, it means that the fittings are made of silumin or plastic, and the braid is made of aluminum.

Reliable products are purchased in specialized stores in high-quality packaging and with markings and a certificate (GOST 6286-73). You must find the service life in the attached passport. If it is less than 5 years old, we do not recommend purchasing such a hose.

The ends must match the pipes to which the flexible hose is connected. The following combinations are possible: nut-fitting (female-male), nut-nut (female-female, as in the photo below), fitting-fitting (male-male).

After the service life declared by the manufacturer has expired, the flexible hose should be replaced.

We focus on quality

Creating durable products requires sophisticated technology and high-quality materials. Handicraft production, which subsequently leads to accidents, is characterized by the following characteristics:

Weak compression of the braid due to the lack of special equipment and the use of sleeves made of low-quality materials.
Low strength and corrosion of connecting elements.
Rapid aging of technical rubber from which hoses and gaskets are made.
Use of ordinary galvanized wire for braiding, the service life of which does not exceed 1 year.

Reliable products have an accompanying passport. High quality products last 10 years. If aluminum braiding is used, this value is reduced by 2 times. The stated period is often exceeded, so it is important to find a reliable manufacturer.

Italian and Spanish companies have proven themselves well. It is worth paying attention to anti-vibration models with a large outer diameter. The equipment eliminates the hum in pipes when using pumps. The cost of such eyeliner is several times higher than that of the domestic one.

High-quality products with a large number of positive reviews are produced by Russian companies “Akvatekhnika”, “Monolit”, “Flexiline”. Stainless steel bellows liners are produced under the German brand WITZENMANN and the Italian PARIGI. Some models are even suitable for heating systems. High quality bellows sleeves are placed in plastic insulation.

Connection rules

The liner in different systems is connected through mounting elements at the ends of the product - union nuts and fittings. The hose model is selected according to its length, type of connection and size of the mounting unit. Fittings are available with cross-sections from 0.5″ to 1.5″. The hose is attached freely, without tension. Otherwise, deformation of the pressed connecting fittings occurs.

For different diameters of the mixer and pipeline, the liner at one end is fixed through an adapter.

During installation, you must follow the connection rules (SNiP 2.04.01-85).

Before installation in the liner, the fastening of the fittings at the ends is inspected, the presence of gaskets, the quality of the thread and braid are checked.
After installation, you need to check the joints within half an hour to see if there are any leaks. When drops appear at the joints, tighten the nuts.
The bending radius should be more than 5–6 times the outer diameter.
The hose is not stretched or twisted during installation.
When tightening, do not apply excessive force: the seal may be damaged. If there is no experience, tightening is done by hand, followed by a slight tightening with a wrench.
The hose cannot withstand open flame or high temperatures.
Once every six months, the tightness of the fastening is checked and an external inspection of the liner is carried out.

Use it in constant flow mode.
Install without gaskets or with mechanical damage.
Operate the product at sub-zero temperatures.

Important conclusion + video

Metal pipes are used less and less for plumbing connections. You can supply water using convenient flexible devices that are easy to attach with your own hands. But this must be done wisely.

Mr. Build recommends: take the selection and installation of flexible eyeliner very seriously, change the sleeve regularly. Carefully monitor the condition of the hose and the integrity of the braid. A burst water line is the most common cause of accidents involving flooding of neighbors below.

Before purchasing and installing, be sure to watch the videos below. From them you will learn:

how to choose the right product, what to pay attention to;
what are the weak points of elastic eyeliner?

Flexible stainless steel hoses are used to connect faucets, toilets and other devices to. When choosing a suitable product, you need to be guided by the basic parameters, a detailed discussion of which is discussed in this article.

Basic parameters for choosing eyeliner

The selection of a flexible hose should be based on the following basic parameters:

type of eyeliner;
scope of application of the device;
hose dimensions;
ways to connect the product.

Types of flexible hoses

The following types of flexible water connections are currently produced:

bellows The corrugated liner is made of stainless steel and has higher performance parameters.

Which is better, bellows or reinforced eyeliner? Comparative characteristics are given in the table.

Any eyeliner can be:

Choosing eyeliner depending on the application

The liner can be used to connect cold and hot water. The purpose is determined as follows:

flexible hose for hot water is distinguished by the presence of a red thread in the braid;

The flexible cold water line is marked with a blue braided thread.

To avoid misunderstandings when using eyeliner, experts recommend purchasing universal flexible hoses that are suitable for connecting water at any temperature. Universal eyeliners are distinguished by the presence of threads of both colors in the braid.

Selection of optimal sizes

How to choose eyeliner size? When determining the dimensional characteristics of the liner, it is necessary to take into account:

hose diameter. The indicator can be determined based on the water consumption of a particular plumbing equipment. It is considered optimal: for connecting a toilet - 8 mm, for supplying water to a sink (kitchen sink) - 10 mm, for a bath - 15 mm;
hose length. The supply line must be connected in such a way that the hose is not over-tightened and unnecessary kinks are not formed. Any defect when connecting the liner leads to a decrease in the service life of the product.

The flexible eyeliner Gigant deserves special attention. It differs from standard products in its increased diameter, as well as increased resistance to mechanical stress and loads. The Giant also has thickened walls, which further increase its reliability.

Possible connection methods

When purchasing a hose, it is important to consider how the liner is connected to plumbing equipment and pipes. The flexible hose can be equipped with:

union nut, which is installed on the outer;
thread for internal connection;

a fitting that connects to the mixer.

When selecting connecting elements, it is important to take into account not only their type, but also the size of the fitting or thread. Otherwise, you will need an adapter to connect the device.

The types of eyeliners, their history, and areas of application are described in detail in the video.

rubber (reinforced) liner must be made of high-quality rubber. Only in this case can it be used to connect drinking water. You can distinguish high-quality rubber from low-quality rubber by smell. Low-quality rubber has a sharp, unpleasant odor;
The braid of the reinforced liner must be intact. The presence of burrs, kinks and other deformations will reduce the service life of the product;
hose flexibility. The parameter is checked in the following way. You need to take the eyeliner by one end and hold it in a vertical position. If the liner bends smoothly, then the hose has sufficient flexibility and integrity. A sharp drop (kink) in the line indicates the use of a low-quality hose or the presence of a hidden defect;
crimping the tip. Weak compression of the tip is a negative characteristic of the liner and leads to a decrease in the service life of the product;
material of connecting elements. Nuts and fittings can be made of aluminum, steel or brass. Aluminum is very susceptible to mechanical stress. Steel is susceptible to corrosion. Therefore, the best option is connecting elements made of brass;

You can check the connection material by weight. Aluminum, unlike brass, is a lightweight material.

manufacturer. It is more advisable to purchase eyeliners from well-known companies that guarantee the quality of their products. The following companies can be distinguished:

"Monolith" (Russia). Flexible eyeliners are produced under the Monoflex brand;
LLC "Neva" (Russia). Eyeliners with Aqualine logo;
Grohe (Germany);
Lavita (Korea);
Altstream (Türkiye).

A correctly selected and installed water supply, subject to all operating conditions of the product indicated on the packaging, can last for a long period of time. Poor quality eyeliner can fail within 3–5 days of use.

A flexible water hose is used to connect the toilet and faucet to the water pipes. Experts recommend choosing eyeliner according to certain parameters, each of which has its own meaning. Read on to learn how to choose and install the hose correctly.

Types of flexible water hoses

The main types of hoses used to connect water are:

reinforced liner. The device is a rubber hose, which is reinforced with metal threads for additional strength. The following can be used as braiding threads: stainless steel, nylon, aluminum;

The most durable are liners reinforced with nylon and stainless steel. The devices can be used to supply water with a maximum temperature of 95ºC at a pressure of up to 20 atm.

bellows liner. The flexible corrugated hose is made entirely of stainless steel. The bellows liner is designed for the passage of water with temperatures up to 250ºС. Thanks to its operating parameters, the hose can be used not only in the plumbing system, but also in.

Types of water hoses differ not only in performance, but also in cost. Reinforced eyeliner can be purchased at a price of 150 - 250 rubles, and a bellows liner for 400 - 500 rubles.

Separation of eyeliners according to purpose

According to their purpose, all water supply connections are divided into devices intended for:

cold water connections;
hot water connections.

The hot water hose is distinguished by the presence of a red thread in the braid, and the cold water connection is marked with a blue thread.

The most commonly found on sale is a universal cold and hot water hose. You can visually identify the device by the presence of both red and blue threads in the braid.

In a public water supply system, cold water quite often gets into hot water supply pipes and vice versa. To avoid problems with plumbing connections and extend the life of the hose, experts recommend using exclusively universal hoses.

Flexible Hose Sizing

The next step in choosing a water hose is to determine its overall dimensions. To find out the dimensions of the hose, you need to calculate:

liner diameter;
liner length.

The diameter of the hose is determined based on the throughput. A thin water hose is intended for plumbing fixtures that do not require quick filling, and vice versa. In order not to calculate the parameter yourself, you can use the average data presented in the table.

The length of the metal braided hose is determined by the following parameters:

the distance between and the connected plumbing product (determined using a tape measure);
hose installation rules that must be followed to increase the service life of the product.

Basic criteria for determining hose length

Defining connection methods

The water supply hose can be produced with various connection methods. The following are used as connecting elements:

a nut designed to attach to an external thread;
thread that connects to the internal thread;
fitting, primarily used for connecting to a mixer.

To determine which connection methods are used in the system, it is necessary to inspect the plumbing product and the outlet from the water pipe.

In addition to determining the connection method, it is also necessary to clarify the size of the thread or fitting.

How to install a flexible hose with your own hands

Basic rules for connection

Before you begin installing flexible hoses, you need to know the basic rules for connecting the device, which are as follows:

It is not recommended to use eyeliner whose braid is broken;
Do not install a hose whose connecting sleeve is not subject to visual inspection;
Do not strain the hose during installation. The liner should be installed freely, but without unnecessary kinks;
If you need to connect the hose from the side, you should pay attention to the bend area. Twisting the liner along the longitudinal axis is prohibited;
to reduce kinks, you can use special adapters that allow you to reduce the radius;
if during the installation process it is necessary to arrange a bend in the hose, then a minimum radius of 70 mm must be observed;
You cannot increase the length of the flexible hose by connecting it to another connection.

DIY installation

To connect a water hose you will need:

wrench or adjustable wrench;
FUM tape (tow), which allows you to seal the connection.

To replace the water hose for the faucet, you must:

turn off the water supply to the plumbing fixture;
remove the eyeliner that has become unusable. To do this, use a wrench (adjustable) of a certain diameter;
Sealing material is wound onto the new liner. Each liner must be equipped with rubber gaskets, but in most cases it is not possible to achieve complete sealing solely with the O-rings included in the kit;
the hose connects to (the toilet);

the liner is connected to the outlet of the water pipe.

It is not recommended to overtighten the threads, as the connecting element may burst, which will require purchasing a new hose. It is considered optimal if you tighten the thread by hand and tighten it with a wrench by ¼ of a full turn.

The method of connecting the water supply to the kitchen faucet is shown in the video.

The correct choice of water hose and compliance with all standards for connecting the device are the key to a long service life of the product. If at least one factor does not meet the established standards, then the line may fail at any time, even with minimal pressure in the system.
