The bellows hose for water is a corrugated sleeve made of special high-quality stainless steel. Such a device is very convenient, but it should be remembered that it is not as flexible as a rubber-metal hose. Bellows eyeliners are used to connect water, air conditioners, gas, and plumbing fixtures such as a sink, shower, and a drain tank. Flexible hoses in water pipes are installed in the last sections of the water pipe, connected from the highway to the devices with which the consumer interacts.
The modern market offers a choice of a large number of bellows liners from different manufacturers, varying in price category, models, functional purpose, color, size, quality, and duration of service. Such hoses are very convenient in everyday life and are always popular with consumers. Now you can safely forget about outdated metal pipes. Almost always, when repairing or updating plumbing, a bellows water connector is used. Customer reviews of these devices are only positive. With the use of high-quality materials, all everyday problems fade into the background.
Eyeliner selection
First of all, you should consider the quality of the materials that were used by the manufacturer for the manufacture of eyeliner. It is worth paying attention to the products of Italian companies made of durable high-quality materials, aluminum and stainless steel. Eyeliners of many manufacturers, having good technical indicators, are distinguished by an affordable price. Some manufacturers are developing anti-vibration eyeliner, which has a large diameter and eliminates noise and hum when connected to household appliances. Such devices have no analogues in the domestic market.
Popular manufacturers
The main manufacturers of such eyeliners are the trademarks Witzenman, Pagri, G-beka and Hydraflex. If the bathroom uses a boiler or some other plumbing, you can not avoid the presence of devices that will catch the eye. In such situations, Hydraflex water bellows are recommended. The products of this company have a modern neat appearance that complements the aesthetic design of the bathroom.
Such eyeliners, of course, are of high quality and can serve customers much longer than ordinary flexible hoses. These devices can be used both for cold water, and for hot. Keep in mind that the cost of branded eyeliner is several times higher than usual.
Appearance
From the proposed assortment, it is recommended to give preference to hoses in which the fitting nuts are made of austenitic steel, since the quality of brass is very low. This material can be recognized by cracks and dents. The seam between the spiral part and the fitting should be performed by argon-arc welding, and not by rolling, as on carved eyeliners. Dark spots are rust, and the too rounded shape of the joints indicates the unreliability and tendency of the material to oxidize. Good seams have a thin and even profile and almost do not differ in color from the hose.
A high-quality bellows-type eyeliner has no dents, rust spots or chips. Their presence indicates the use of base steel. This is considered a sign of poor metal strength. Protected eyeliner has, as a rule, a coating of PVC film. The difference between products for gas and water most often lies in the stiffness of the spirals due to the calculation of the interaction with greater or lesser pressure. This is checked by the method of ordinary stretching the hose.
Operational Features
Many manufacturers officially guarantee that their hoses will last 15 years. A good Akvaprof bellows for water, for example, can be easily operated for 30-35 years, and under gentle operating conditions this indicator stretches to fifty. Service life also depends on fitting materials. The minimum service life is observed for carbon steel and brass elements. Stainless steel nuts are the most durable when compared to other materials.
The design of the spirals makes it possible to twist the hose, and the bend will be fixed. High-quality stainless steel bellows for water can stretch 1.5-2 times without any risk. Due to the rigidity of the corrugated structure, its diameter should not change. Choosing a hose, you can ask the seller to step on the eyeliner or put some kind of cargo under it.
Benefits
Modern bellows water inlet makes it possible to quickly install plumbing, various water supply devices, gas and heating equipment in the most inaccessible places in the country, in a cottage, apartment or office. High-quality hoses have high technical indicators, anti-vibration properties and are indispensable for organizing comfortable conditions in any room. The remarkable aesthetic properties of flexible eyeliners make it possible to emphasize the stylish interior of an apartment or office.
What is the difference between a bellows water connector and metal pipes?
The familiar iron pipes have been used less and less. When connecting water supply, heaters, bidets and other devices, bellows hoses made of polymer materials, rubber and metal are increasingly being used. This eyeliner for water is very flexible, does not rust, is resistant to various aggressive environments, as well as temperature extremes, has an extended service life.
Eyeliner design
A hose is an essential element of a bellows connection. It can be made of non-toxic rubber of various grades, as well as other materials. Used components must be environmentally friendly, not form harmful compounds on the walls and withstand relatively high temperatures. Rubber hoses are protected externally with a braid made of stainless steel, aluminum and other materials so that the bellows hose for water is not subject to mechanical stress and has a sufficiently high strength.
All connecting elements - fittings, nuts with gaskets, nipples must always be made of sufficiently high-quality materials.
How to install a bellows water connector
Reviews of numerous users indicate the simplicity and ease of installation of such hoses. Inexperienced wizard will not be difficult to understand the installation process . Installation of the bellows eyeliner begins with the removal of pipe structures. Work in close proximity to fire sources and at low temperatures is strictly prohibited. Water inlet must be carefully examined for kinks, bends, and other damage. Using special valves, these hoses can be interconnected.
It is necessary to ensure that everything is tight at the joints. All stainless steel bellows for water should be checked for leaks every six months.
Eyeliner for washing machines
Many modern apartments or offices have washing machines, dishwashers, air conditioners, water heaters and other household appliances. A suitable bellows flexible water connection is always required to connect devices. Manufacturers provide standard hoses no more than 1.5 meters in length complete with equipment.
If necessary, everyone can buy a genuine eyeliner. Italian products have proven themselves in the best way. It has a sufficiently high strength and heat resistance. There is no domestic production on the market yet.
Consumer Reviews
In many specialized stores or on trading floors on the Internet, there is a bellows eyeliner for water. Customer reviews of purchased products indicate that preference is mostly given to Italian manufacturers, despite the high cost of the fixtures. In online stores, buying a bellows eyeliner is much more profitable.
What is fraught with the acquisition of low-quality devices?
Purchasing a bellows eyeliner from unreliable suppliers can cause a lot of trouble during operation. Poor-quality appliances have a very short lifespan, and the entire system requires regular inspection.
A bellows connection of this type should be replaced with a new one six months after installation. There is a high probability that a poor-quality hose will burst and water will pour into the apartment located a floor below. Naturally, after this you will have to pay for the repair work.
Conclusion
When installing water connections today, metal pipes are no longer used. Convenient flexible devices have come to replace the old ones, which are easy to attach and look aesthetically pleasing, distinguished by their durability, quality and reliability.
