Stop Valve

Description

TECHNO PPR fittings are made of Polypropylene Random Copolymer PP-R as per the standard ISO 15874-3 and DIN 16962.

The Polypropylene is the most reliable material has excellent characteristics rigidity, homogeneous joints, high temperatures resistance. Hence PPR piping system shall preferred for safe and reliable long-lasting life in hot and cold-water distribution, Techno Plastic proves to be the most trusted piping system
