Wavin Osma mUPVC Solvent-Weld Waste Reducer (White) 40 to 32 mm – 5M455W

A solvent-weld reducer that adapts from a 40 mm pipe into a 32 mm pipe, ideal for gravity drainage systems needing size transition. Constructed from durable PVC‑C, it's UV- and heat-resistant, fire-retardant, and certified to BS EN 1566‑1:2000, suitable for both interior and exterior use.

• Enables permanent, leak-proof connections using PVC-C cement.
• Short and effective—ideal where space is limited and pipe sizes vary (e.g., basin outlet to main stack).
• Maintains integrity under sun, heat, and minor fire exposure—works for outdoor installations.
