PPR Reducing Coupling

Product Overview

The PPR Reducing Coupling is a PP-R socket fusion fitting designed to connect two PPR pipes with different diameters in hot and cold water piping systems. Manufactured from polypropylene random copolymer (PP-R), it provides a practical solution for changing pipe diameter while maintaining a reliable fused connection.

The fitting uses socket fusion, with the pipe and fitting socket heated and joined to form an integrated connection after cooling. Its smooth internal surface supports efficient water flow, while the corrosion-resistant PP-R material provides reliable performance in compatible residential, commercial, and building water supply systems.

Product Description:

Applications

Hot and Cold Water Supply — for connecting different pipe diameters in compatible PPR hot and cold water systems.

Residential Plumbing — for pipe size transitions in domestic water supply installations.

Commercial Buildings — for connecting different PPR pipe sizes in hotels, apartments, schools, and other building plumbing systems.

Water Supply Pipeline Systems — for changing pipe diameters while maintaining a fused PPR connection.

Key Features

PP-R Construction — manufactured from polypropylene random copolymer, offering lightweight handling and good corrosion and chemical resistance.

Reducing Connection Design — connects PPR pipes of different diameters within the same compatible piping system.

Socket Fusion Connection — creates an integrated pipe-to-fitting joint through controlled heat fusion and cooling.

Smooth Internal Surface — helps reduce flow resistance and limits scale buildup inside the fitting.

Reliable Sealing Performance — the fused joint provides secure connection integrity when properly installed.

Hot and Cold Water Compatibility — suitable for compatible PPR water supply systems for both cold and hot water applications.

Lightweight Installation — PP-R construction facilitates handling and installation compared with conventional metal fittings.
