110mm Pipe Extension Fitting – The Essential Problem-Solver for Drainage Layouts
The Pipe Extension Fitting (also known as a socket shifter or slip coupler extension) is the go-to hardware for correcting alignment errors or reaching awkward termination points. Whether you’re working on a new soil stack or an underground sewer run, this fitting provides the necessary flexibility to complete a run when the existing pipework is insufficient. At ECO Heat Shop, we provide the trade-standard hardware and PVC-U fittings required to make every drainage project seamless and secure.
Engineered for Strength and Versatility
Manufactured from high-impact, UV-stabilized PVC-U, this extension fitting is built to handle the rigours of both above-ground and subterranean environments. The spigot end slides into any standard 110mm socket, while the integral socket end accepts the next section of pipe, effectively “extending” the reach of your system. Its smooth internal bore maintains the hydraulic efficiency of your waste line, ensuring that water velocity is not compromised by the additional joint. This hardware is a must-have for renovations where existing pipe positions are fixed and difficult to modify.

ECO Heat Shop Tip: When using an extension fitting, always ensure the pipe is pushed fully home into the socket to the depth mark. This is a sustainable plumbing choice; by using a dedicated extension fitting rather than a series of small offcuts and couplers, you reduce the number of potential leak points and maintain a smoother flow path for waste. Always use silicone lubricant on the seals to ensure the hardware seats correctly and stays watertight for decades.
