Details

The 50mm (55mm) to 40mm (43mm) White Solvent Weld Reducer provides a simple solution for connecting 1.5″ and 2″ pipe sizes within a high-capacity waste system. Because this fitting glues directly into the socket of a 55mm elbow, coupler, or tee, it allows for a seamless reduction down to 43mm 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 commercial runs and standard kitchen or bath wastes.

Installers often encounter systems where a large 2″ main run must connect to a 1.5″ branch, often resulting in bulky, mismatched connections that look unprofessional. Additionally, the common confusion between 40mm/43mm and 50mm/55mm sizing frequently results in users purchasing the wrong fittings for their solvent weld systems. This Solvent Weld Bush Reducer solves these issues because it provides the correct 55mm-to-43mm fit for a flush 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.
