In addition to the standard size range of fittings can be manufactured for a specific welding equipment. If you want to connect non-standard fittings, manufacturers are ready to release a batch of special sizes. At larger sizes it is important to follow the alignment of elements, and installation of the fittings must be in strict accordance with the rules.

The use of PVC pipes implies a corresponding fittings. The most suitable compound are PVC fittings. These joints possess all the qualities of plastic pipes. They do not rust, are not subject to corrosion. Reliability of PEX compounds are tested by time and durability meets durability of PEX tubing.

Connecting PVC pipe fittings from the same material, we have a pipeline system with the same parameters of thermal expansion, which has a positive effect on the reliability of the weld. Connecting with sleeves made of PEX can hold out long enough line, using a tube of limited length. This point is important when laying large diameter pipe. Small diameter pipes are more flexible, can be transported by those twisted. Large diameter pipe can be bent, and the length of the vehicle is usually enough. Installation of PEX pipe fittings are faster than the metal. The average speed of installation of PEX fittings in three times higher.
