Product Introduction
PPR reducing couplings are hot-melt fittings used to connect PPR pipes of different diameters. They are widely used in hot and cold water systems, floor heating networks, and central air conditioning circulating water systems.
Product Advantages
High Precision
Using CNC precision molds and fully automated injection molding, dimensional tolerances are controlled within ±0.05mm.
Safe and Non-Toxic
Complies with EU EN ISO 15874 standards and contains no plasticizers, heavy metals, or harmful leachables.
High Pressure Resistance
Made of high-molecular PPR material by injection molding, with pressure resistance up to 2.0 MPa.
