Fittings are necessary to ensure a strong connection of the pipe to each other. Otherwise, leaks may occur, which is extremely undesirable for the water supply. We now tell you how to choose the right fittings for pipes made of polypropylene.

Yes, it seems that there are a lot of types of fittings. It is enough to go to the pages of any thematic store to make sure of this. For example, a good choice would be a site https: // ktk. kiev. ua / vodosnabzhenie / fitingi / polipropilenovye-fitingi /. However, it is important to learn how to orient their types, which are only three:.

Metal compression (this includes the Eurocone);.

Polypropylene for soldering;.

Metal Crimping Fittings.

When choosing fittings, it is worth considering that a metal fitting placed in concrete is exposed to stray currents. Who are able to destroy the connection in 15 years. Therefore, if the pipeline is filled with concrete, you should stop the choice of soldering fittings. They are also suitable for regular domestic water supply, if you will lay it yourself (a special soldering iron is quite easy to buy, and you will learn how to work quickly).

Crimping fitting requires careful attention. Not every manufacturer indicates the size and thickness of the walls. Instead, there may be another parameter (for example, the ratio of the thickness to the diameter of the pipe) that can confuse an unsophisticated user. In this case, the diameter of the fitting must be slightly less than the diameter of the pipe. Otherwise, when connecting, one of the elements will be damaged.

At the same time, too small a diameter of the fitting will lead to the fact that it will "walk" inside the tube or even drop out altogether.

Also always be interested in the certificate of conformity. If it is - the goods were produced or imported legally. If there is no certificate, there are either illegal products or forgery. By the way, try to buy fittings and pipes from the same manufacturer - this ensures that they are ideally suited to each other.
