Flexible hose: secrets from the plumber. We check right in the store so that it does not tear and flood neighbors
Jan 04, 2021
Flexible hose with protective braid is used to connect to plumbing equipment pipelines. Not suitable for heating systems. Does not withstand high temperatures. The most popular places where it is irreplaceable: connecting a toilet bowl, faucets, shower cubicle, washing machine, boiler.
Braided rubber hose with union nuts, gaskets and fittings. That's what flexible eyeliner is all about.
When choosing, consider the diameter of the pipe, as well as the purpose of the liner. Products for hot and cold water are available for sale. There are universal ones on sale (ribbons in red and blue are woven). Cheap products don't have any color marks.
Expensive eyeliners are made from a special rubber made of elastic and non-toxic rubber. Cheap eyeliners are made of low-quality, brittle, brittle rubber.
How to distinguish a quality eyeliner in a store?
A common problem with liners is cracking from exposure to water. It is better to avoid bending or twisting during further work. Otherwise, the sheath may deteriorate.
For braids material is important. The shirt is made from aluminum filaments. Such liners do not last long, they are afraid of condensation, which leads to oxidation and weakening of the reinforcement. In the store, such an eyeliner can be checked as follows. If you run over white paper, a gray trail will remain. If the eyeliner is magnetic, then it is not aluminum.
There is also a braid from galvanized, stainless steel, nylon. Stainless steel will last longer (up to 10 years). Nylon performs better than stainless steel. Service life over 15 years.
When choosing in a store, pay attention to the label. The eyeliner shouldn't be very light. You can find on sale a flexible eyeliner with fittings made of fragile silumin, which begins to crumble over time. A liner with plastic fittings is also not worth buying.
Rubber hose Is also a selection criterion. Ask the seller what kind of rubber the product is made of. You can define quality yourself. Usually toxic rubber gives off a pungent odor. Twist the eyeliner in your hands. It doesn't have to be "oak".
Fittings should be well pressed. Compression sleeves must be made of stainless steel. There is such a test method: scratch the nut with a metal object.
If a yellow color appears in the scratch, then it is brass. And when the mark under the scratch remains the same or dark, then it is better not to take such an eyeliner.
By the way, nut does not require a thread seal. There is a gasket that will provide the desired connection and there is no need to wind anything. A huge mistake is winding any sealing material on the thread.
The best eyeliner for price and quality: stainless steel rubber sheath with brass union and nut. If you are afraid of leakage, and the line is in doubt, install a safety valve.
