Cosmoplast PPR Reducer Bush, 50 × 40mm, Heat-Fusion, Compact Step-Down

The reducer transitions from a 50 mm PPR pipe to a 40 mm PPR pipe, enabling seamless size changes within the same system.

It’s made from durable polypropylene random copolymer (PPR) and is designed for heat-fusion (fusion-weld) connections, providing homogeneous joints with good thermal and chemical resistance for potable water and related applications.

For fusion-weld installations: cut and deburr both pipe ends, dry-fit to ensure proper alignment, clean the pipe ends, heat-fuse the 50 mm side and the 40 mm side separately according to your fusion tool’s instructions, press together to form a tight seal, and allow it to cool undisturbed before testing for leaks.

Yes. It’s designed for potable water systems and hot/cold water piping, offering corrosion resistance and a non-toxic composition suitable for residential and light industrial use.

It is engineered to withstand typical high-temperature and higher-pressure water systems encountered in residential and industrial settings, but always ensure the overall system design complies with local codes and the specific pressures you expect.

Compared to metal reducers, this PPR reducer resists corrosion, provides a leak-free fusion joint, is non-toxic for potable water, and generally offers easier, faster installation with lower material costs.

If you’re stepping down from 50 mm to 40 mm, this reducer is the direct fit. Ensure the fusion process is properly performed and verify that your system pressure and temperature are within the fittings’ supported range.

After cooling, perform a pressure test specific to your system. If you notice any leaks at the fusion joint, depressurize and recheck the joint alignment, re-cut if needed, and re-fuse. Ensure the pipe ends were clean and deburred prior to fusion.

If you want to compare options, you can consider: Cosmoplast PPR Reducer Bush 50x32 (URL: https://fepy.com/product/cosmoplast-ppr-reducer-bush-50x32) and Cosmoplast PPR Reducer Bush 40x32 (URL: https://fepy.com/product/cosmoplast-ppr-reducer-bush-40x32). These provide similar fusion-weld compatibility with different size reductions, so you can pick the best fit for your piping layout.

Pair it with compatible PPR pipes and fusion-wusion connectors such as 50 mm and 40 mm PPR pipes, end caps, tees, and elbows from the same or compatible PPR range to ensure consistent fusion quality and system integrity.

Yes. Ensure clean, deburred pipe ends; confirm proper pipe straightness; use correct fusion settings for the PPR material; apply even pressure during fusion; allow adequate cooling time before testing; and verify joints under safe pressure conditions after installation.
