Specifications
To begin with, consider the main parameters of a metal hose made of galvanized steel. The starting material for the manufacture of this type of hose is a galvanized metal plate with a thickness of three microns. The gap between the turns of twisted plates is sealed:
- cotton fabric for products of the brand RZ-CH;
- polypropylene film for RZ-SL products.
The features of this design provide the flexibility of the mounted cable routes, reliable protection against damage and the effects of dust and dirt, and the option with a polypropylene seal allows you to withstand intense moisture loads. These characteristics make it possible to successfully use these hoses when installing both open and hidden wiring. The use of this type of cable protection is recommended in electrical circuits servicing ventilation, heating and air conditioning systems.Due to the metal sheath, which provides a high degree of protection against fire, the sleeve can be used for mounting open wiring on wood. The metal plate from which the electrical product is twisted serves as a shield and protects the wiring from electrical interference. Based on the above material, the main advantages of a metal hose can be distinguished:
- Strength and ability to withstand mechanical damage.
- The ability to provide protection from dust, dirt and moisture.
- High degree of fire safety.
- The ability to withstand the effects of electrical interference.
Taking into account the needs of electrical installation, manufacturers have mastered the production of a very wide range of internal diameters of metal hoses, from 10 to 100 mm.
Technical characteristics of metal hoses of RZ-TsKh and RZ-SL grades:
Now consider a metal hose in polyvinyl chloride (PVC) insulation. Popular brands: RZ-CP and MRPI. The manufacturing technology of this type of hose and the set of positive qualities remain the same as for previous products. The difference is that they are made with an insulating PVC coating, which provides a higher degree of protection. The presence of an insulating layer classifies this type of metal hose as a hermetic construction with high resistance to corrosion, which makes it suitable for use in underground utilities, tunnels and in explosive areas.
It is especially important to know that this type of hose is by no means adapted for work under water, as well as for laying outdoors, in regions with low temperatures. The fact is that the PVC sheath is destroyed in the cold.
It should be noted that this option has another important significant plus - in the event of a breakdown of the cable sheath, the insulating layer localizes the spread of current leakage beyond its limits, which will protect maintenance personnel from electric shock upon contact with it.

Method number 2: heating
When the nut is rusted, what will help to unscrew if the previous method is ineffective? Try to heat the part - due to the high temperature, the metal will begin to expand, thereby destroying the layers of rust. The threaded connection from this, in turn, will lose strength.
What can be used as a heater:
- Gas burner.
- Lighter.
- Building hair dryer.
- Blowtorch.
In extreme cases, ordinary boiling water will help you. Be careful not to use the heater in close proximity to wood or painted elements.
The instructions for your actions are as follows:
- Heat the nut to a high temperature, preferably red hot.
- The next step is to try to unscrew it with a key.
- If the nut or bolt thread is damaged, it is necessary to weld the end head to the nut, and then heat up the entire structure. Try turning it off with a wrench.
Collector wiring of water supply pipes
Most often, such a wiring is mounted where it is planned to hide pipes under plaster or decorative panels, run pipes underground or cast them into a concrete floor screed.
The advantage of collector wiring is that each consumer (plumbing fixture) has its own separate line, which departs from the common collector. With such a decoupling, at any time it is possible to block a separate point without detriment to other devices.With such a decoupling, a uniform distribution of water occurs, so the pressure (pressure) at all points will be the same.
The only disadvantage of such a system is the price, which includes a significant footage of pipes and fittings, as well as manifolds (distribution combs) with shutoff valves.

Selection Tips
We will introduce you to several useful recommendations that will allow you to correctly determine the choice of flexible fittings for your faucet.
- Read the label carefully, check the specifications of the device, check the manufacturer. All of them must meet your requirements and the plumbing used.
- Check if the eyeliner seems very light. If so, then most likely aluminum served as the material for the braid, and the fittings were made of low-grade metal. Over time, such elements simply collapse.
- In no case do not buy a product if its fitting is made of plastic. This is the worst option on the market.
- Check the eyeliner for "oakness". That's why it is flexible to be elastic. Lack of elasticity indicates poor hose quality.Over time, cracks will appear inside it, or it will burst completely.
- Make sure that the fittings are well pressed, the tubes are fully inserted, and the compression sleeves are made of stainless steel.
- Take a look at the cap nuts. Sometimes they are very light or too thin. Lightness suggests that the fitting may be plastic, or the nut is simply made of low-grade metal. This leads to leaks. The best option is nickel-plated brass. You can check whether it is used or fake by a simple scratch.
- Smell the eyeliner. For all the comical advice, he will give a lot to understand about the product. The presence of a pungent odor indicates the use of technical rubber that is dangerous to your health. As a rule, such phenomena are characteristic of cheap eyeliners and mixers.
- Purpose. Each eyeliner has its own specialty, so to speak. There are products for hot water, cold, as well as universal models. This is indicated by a red or blue braid, respectively. As for universal options, both colors should be present there.
Security measures
Be sure to take into account the fact that the eyeliner is under constant load. They occupy the working area of the pipeline. This leads to potential danger.
If you are not at home for a long time, the water pressure may increase, the product will not withstand the stress, it will burst. As a result, you will flood yourself and your neighbors. The consequences are difficult, long and financially costly to eliminate.

As you can see, flexible eyeliner has its undeniable advantages, but it is also characterized by disadvantages. In fact, the main reason flexible systems are not fully trusted is because many products are of poor quality.
An attempt to save on the arrangement of the water supply system often entails much more serious financial losses. It makes no sense to blame the manufacturers of cheap eyeliners, since you alone are responsible for repairing your home. Do not spare money, buy a quality product right away. The eyeliner, in turn, will answer you with a long and reliable service.
Common Problems
Over time, eyeliner can give slack, provoke the appearance of certain problems. There are popular reasons why the device fails:
- Weak or poor-quality braided crimp;
- Low quality of connecting elements and components, such as nuts, bushings, fittings;
- Use of rubber and braid materials for low grade hose.
Similar problems, as practice shows, arise when purchasing products from dubious sellers and from unverified manufacturers. But in recent years, such situations are becoming less and less.
It's easy enough to explain. Manufacturers, in an effort to win the trust and favor of customers, improve product quality, use the best raw materials. As a result, now most hoses are made of specially treated rubber, nuts and bushings are made of brass, and braids are made of steel, which is not subject to corrosion and is not afraid of water.
Modern fittings have saved the flexible type eyeliner from its weak point - seals. Now a number of products do not include seals, since the fitting fully replaces them.
Kitchen faucet installation
Replacing the faucet in the kitchen is nearing completion. Now we assemble the crane and install it in place. It is much more convenient if the work can be carried out on a removed sink. If this is not possible, all manipulations will have to be carried out reclining in the closet. Approximately as in the photo.
Not the most comfortable position
Assembly
First, we fasten flexible hoses to the mixer. They are screwed in by hand, then tightened a little with a key - no more than 2 turns.
We screw the flexible hose into the holes on the mixer body, tighten it slightly with a wrench
Now you need to put a rubber gasket on the body, which seals the junction of the mixer and the sink surface. This rubber ring of decent diameter is included in the kit. It is pulled through the installed supply hoses, placed on the body.
Install gasket on body
In modern kitchen faucets, there are two different forms of attachment to the sink. The first - with the help of a nut - you saw in the part where it was about dismantling the mixer. It's just an "older" system. The second provides for the presence of rods and spacers-clamps in the form of a horseshoe. The rod is usually one, but there may be two. If there are such rods, they are screwed into the appropriate socket. If a nut is screwed on it, it is removed.
Rod for additional fixation
Installation on the sink
Now the kitchen faucet can be installed on the sink.First, flexible hoses are inserted into the hole, then the body is placed in the center of the hole. Further actions depend on the type of fastener. If this is an ordinary nut, they simply tighten it, trying not to overtighten it.
The nut is screwed onto the body
If it is a model with rods, the appearance is different, although the meaning is the same. First, the gasket is put on (it is also in the shape of a horseshoe), then the pressure plate. Next, the nuts are screwed onto the rods. The nuts are slightly tightened with a wrench. TODE nothing complicated.
Faucet attachment with rods
Turn the sink over and turn on the faucet. He must be dead. There shouldn't be any loopholes. If there is movement, tighten the mount.
Washing installation
Now the sink with the mixer installed on it is placed in the prepared place. First, a silicone sealant is applied from the back of the sink around the perimeter (not acrylic - it quickly turns yellow). Then the sink is installed in place, the fixing bolts are tightened.
Preparing the sink for installation
Then everything is simple: put in place, align with the edges of the table, tighten the fasteners. It is made in the form of petals that attract the sink to the countertop when you tighten the nuts. The sink must stand firmly, without shifts.
Connecting hoses and siphon
With a siphon, everything is simple - they pulled the corrugated hose to the nozzle, tightened the nut by hand until it stops. All. Do not use the keys - everything is made of plastic.
With the connection of the water supply is not much more difficult. Just be sure not to confuse the place of connection of cold water. Its entrance is on the right. After making sure that there is a rubber gasket in the union nut of the flexible liner, we bring it to the pipe, tighten the nut as much as possible with our fingers. Then we take the key and tighten it one or two turns.Do not pull hard - you can cut through the gasket and then the connection will flow.
But what about tow, winding and paste? When using hoses of normal quality, they are not needed. Connection without them is reliable and tight. It will be possible to rewind a lot if, after a test run, drops of water appear from under the nuts. But this shouldn't be. There is no need to wind tow or fum-tape just like that. Extra time and extra pressure on the union nut.
After connecting to the hot pipeline, we can assume that the independent replacement of the faucet in the kitchen is over. It remains to turn on the water and check if everything is working properly and if the connections are leaking. To do this, the joints are wiped with a dry cloth, and then carried out several times by hand.
Manufacturers overview
In order not to delay the choice of the right products, it is necessary to familiarize yourself in advance with the most trusted and sought-after companies that are included in this list.
- Grohe (Germany). The company produces high quality eyeliner that attracts customers with reliability, ergonomics and service life.
- ProFactor is a German brand with 50 years of experience in this field. During this period, the products have shown themselves on the world market from the best side and today are the indisputable favorite. Any sample from the ProFactor range is an example of high quality.
- Remer is a brand originally from Italy, which creates a strong competition for the products presented by the companies above. This product is well known to the domestic consumer. The company carries out the entire production cycle, which makes it possible to control each stage.
- Consumers have an ambiguous opinion about the products of the Russian company Santrade.In some cases, they are satisfied with the work of eyeliners and have no claims against the manufacturer, while in others, users have negative ratings. Santrade manufactures products in a variety of price ranges. Inexpensive range is not of high quality. As a result, there are differences of opinion.
- The Spanish manufacturer Industrials Mateu is consistently engaged in research and development activities and exercises strict control over its own products. Such a concept of work enables her to produce a sought-after product that meets international standards.
- Rispa is a company about which little is known. According to some data, this is a manufacturer from Turkey, and from other sources it becomes clear that it was created in China. The products are inexpensive, which gives it the opportunity to stay on the Russian market. In addition, the quality of the products is far from the worst. Faucet liners can last a decent amount of time even with very frequent use, so if you have a small budget, you can opt for these products.
Flexible piping tips
Before choosing a flexible eyeliner, take it in your hands and look carefully at the external condition. Evaluate what this eyeliner was made of. If you are unable to assess with your amateur eyes, then ask the sales assistant. In the event that the seller answers elementary questions about the choice of products that the weather is wonderful today, then it is better to contact another seller or choose another store. It is advisable to purchase all plumbing only in specialized stores.You need to clarify the composition and performance characteristics of the purchased flexible eyeliner.
It is also necessary to find out what materials it was made of - this is very important. In addition to the standard aluminum or steel braid, there is a third material - nylon
It is known for its strength and durability, in addition, it is safe for human health. True, there is still one minus in this material: nylon eyeliners are an order of magnitude more expensive than their counterparts. Due to the high cost, not everyone can afford to install nylon eyeliner.
For a visual comparison, you need to pick up two flexible eyeliners. Conduct a visual assessment: if one of the options is too light, then it is most likely a low-quality fake. As a rule, such parts are made from poor materials that will fail very quickly. Often, manufacturers produce eyeliners from aluminum flare nuts, which can easily crack without a serious reason.
When choosing products, pay attention to the flexible qualities of the eyeliner. The material should be elastic, it should be soft and bend in different directions without much effort.
The rubber hose of cheap eyeliners, as a rule, does not bend at all and when you try to bend it, it simply breaks.
If the fitting is made of plastic, then it is better not to buy such products - most likely, after a few weeks of operation, it will leak. In some cases the fitting can simply break off from the nut, and it will crumble into small pieces. It will break into pieces on its own, without the use of any physical force.
Eyeliners can be made for different temperature conditions, based on this they can be:
- for cold water;
- for hot water;
- universal.
There are special tapes for recognition. For cold water, a blue tape is installed on the eyeliner, and for hot - red. On universal types of eyeliners, there are two tapes at once.
Many experts recommend installing universal flexible eyeliners, since they can last an order of magnitude longer than specialized cold or hot water pipes.
The thickness of the eyeliner nuts is what you need to pay attention to when buying. Cheap low-quality goods have a small thickness, as a result of which the eyeliner under the influence of water may fall apart over time
I mean the cap nut. It is necessary to pay attention to the thickness of the union nuts not at home, when you unpacked the purchase, but also in the plumbing store. Many buyers do not consider it necessary to inspect the design of the purchased eyeliner, so they have to repeat such a purchase after some time. In high-quality eyeliners, the thickness of the nut is at the proper level, they are more durable than their cheap counterparts.
Connecting hose arrangement
Having dealt with the types, we will consider for a general acquaintance the typical design of a flexible eyeliner.
Rice. 7. Design of flexible pipes for faucets
The product consists of the following main elements:
- Sealing gaskets to ensure the tightness of the connection and prevent leakage "A".
- Brass or steel nipple "B".
- Rubber or rubber hose "C".
- Aluminium, stainless steel or nylon "D" protective braid.
- Press sleeve (clamping nipple) "E".
- Connecting fitting (steel or brass) "F".
- Union nut "G".
The eyeliner is made with a connection of three types: nut-nut, nipple-nut and nipple-nipple. The standard dimensions for the nut are 1/2", for the fitting - M10. Sometimes a non-standard connection may come across, such as an M8 fitting or a 3/8" nut. In this case, you will need an appropriate adapter for a kitchen faucet or other equipment.
The length of flexible hoses can be from 500 to 2000 mm, we advise you to choose the appropriate size so as not to install extension pipes.
Note that the fitting can be short and long. The latter is more convenient to connect the mixer.
