The 110mm Push-Fit Soil Double Socket Straight Coupler (Black) is a heavy-duty uPVC inline connector designed to join two plain-ended sections of 110mm black soil pipe in a straight line. It is ideal for lengthening existing pipe runs, repairing damaged sections, or connecting cut lengths during installation.
 
Featuring two opposing sockets equipped with integrated captive rubber ring seals, the coupler allows both pipe ends to push straight in effortlessly. The internal central stop rib ensures that the pipes insert to the correct depth, creating an immediate, permanent, and watertight expansion joint that accommodates natural thermal movement along the stack.
 
Manufactured from high-impact, UV-stabilized uPVC in compliance with UK standards (BS EN 1329-1), the black finish resists weathering and discoloration, matching standard black commercial and domestic drainage systems. It provides a reliable, leak-free connection for both internal waste stacks and external above-ground drainage networks in accordance with UK Building Regulations (Approved Document H).
