Technical data:

The restrain system is effective independently of the sealing of the pipe, which is secured by a tighten- ing ring. Universal sockets due to their wide range of pipes are suitable for repairing or damaging an existing pipeline.

The universal coupling type U is designed to directly insert the pipe directly from both sides. For PE / PVC pipes, we recommend the performance of universal sockets with a tightening ring - a restrain, which can be ordered for other pipe types, but not necessary. With the restrein system, there is high safety to the extraction of PE / PVC pipes from universal socktes that can be caused by hydraulic shock, low outside temperatures in which plastic tubes are collected, lack of telescopic MDK pieces or com- pensators on long pipelines, swaying terrain, etc.

Each universal connector of non-removable type - restrein, can also be used for PE / PVC pipes, and by removing the clamping ring and lid, it is possible to apply in the complete coupling range. For example: Universal socket DN 80 non-detachable type - restrein has application on PE and PVC pipes OD 90, and if the clamping ring and lid are removed, the same universal coupling can be applied on all types of pipes of external diameter from 88 to 107 mm.
