The Solvent Weld Reducer White 40mm / 32mm is an essential stepping fitting designed to join a smaller 32mm waste pipe directly into a larger 40mm waste pipe run or fitting socket. Manufactured from high-impact PVC-U, this white concentric reducer provides a smooth internal transition between pipe sizes, allowing wastewater from smaller fixtures like bathroom basins to discharge efficiently into main 40mm drainage lines without causing flow restriction or turbulence.
 
Engineered with a 40mm spigot (male outer diameter) on one end and a 32mm socket (female inner diameter) on the other, the fitting allows for compact inline size reduction within tight plumbing spaces. When assembled using standard solvent cement, the plastic surfaces chemically fuse together, creating a permanent, unified bond that is completely watertight, airtight, and resistant to joint separation over time.
 
Ideal for both concealed service voids and exposed domestic plumbing layouts, its clean white finish matches standard waste pipe networks. Built to withstand continuous exposure to hot water discharge and harsh household cleaning chemicals, this reducer offers professional plumbers and home improvers a simple, dependable solution for integrating varying pipe sizes across domestic waste systems.
