The Pushfit Waste Socket Reducer Grey 40mm - 32mm (also known as a reducer bushing or socket reducer) is an adapter fitting designed to reduce a 40mm push-fit socket down to accept a smaller 32mm waste pipe run. Manufactured from high-impact grey polypropylene, this component allows seamless step-down integration between different pipe diameters within a domestic drainage network.
 
Equipped with a 40mm spigot end and an internal 32mm push-fit socket with a factory-fitted elastomeric rubber lip seal, the reducer pushes directly into any standard 40mm fitting socket without requiring solvent cement. The elastomeric seal creates an instant, watertight join around the incoming 32mm pipe while absorbing thermal expansion and contraction cycles from hot water discharge.
 
Ideal for connecting smaller 32mm washbasin or bidet waste lines into a larger 40mm main branch pipe, this reducer ensures smooth, stepped flow without causing backpressure or turbulence. Resistant to continuous hot water and common household detergents, it provides professional plumbers and DIYers with a clean, reliable, and space-efficient sizing transition.
 
Pushfit Waste systems are highly adaptable and manufactured to BS EN 1329:2000. They are fully compatible with other systems.
