Details

The 40mm (43mm) to 32mm (36mm) White Solvent Weld Reducer provides a simple solution for connecting two different pipe sizes within a 1.5″ waste system. Because this fitting glues directly into the socket of a 43mm elbow, coupler, or tee, it allows for a seamless reduction to 36mm pipework. We manufacture this bush from high-quality UPVC, so you can solvent-weld it to create a permanent, airtight connection. Furthermore, this bond offers far more reliability than standard step-down adapters. Consequently, the fitting resists heat and chemicals, which makes it perfect for transitioning between larger kitchen runs and smaller basin wastes.

Installers often encounter systems where a 1.5″ main run must connect to a 1.25″ appliance or basin trap, leading to bulky, mismatched connections. Additionally, the common confusion between 32mm/36mm and 40mm/43mm sizing frequently results in users purchasing the wrong adapters that lead to leaks. This Solvent Weld Bush Reducer solves these issues because it provides the correct 43mm-to-36mm fit for a flush, professional finish. Once you apply the solvent cement, the fitting creates a unified joint that will not vibrate loose or fail under pressure. Therefore, you achieve a clean, permanent result while avoiding the common pitfalls of complex pipe transitions.
