PPR Socket Fusion Reducing Coupling

This PPR socket fusion reducing coupling is injection‑molded from premium random copolymer polypropylene, designed for connecting PPR pipes of two different diameters in hot‑cold water piping systems. It adopts socket fusion welding to form integrated leak‑proof joints.

Optimized transition inner cavity reduces flow turbulence and pressure loss at diameter‑changing section. Food‑contact safe raw material meets potable‑water standards, enduring continuous working temperature up to 95℃ with outstanding anti‑scale and anti‑corrosion performance. Complying with ISO15874 standard and PN25 pressure rating, it achieves over 50‑year service life. Widely used in residential plumbing, commercial water supply and floor‑heating installations.
