Effortless Installation: Features dual rubber “captive” seals for a secure, leak-proof push-fit connection without solvent weld.
UV Stabilized: Specifically manufactured in black to resist sun damage and brittleness during external above-ground use.
Full Compatibility: Standard 110mm (4-inch) diameter fits all major UK soil and underground drainage brands.

A 110mm straight coupler (also known as a double socket coupling) is the industry-standard fitting used to connect two plain-ended lengths of 110mm soil pipe. It is an essential component for extending vertical soil stacks, repairing damaged sections of pipe, or transitioning between different parts of a gravity-fed waste system.
In the UK, colour coding is vital for building regulations. While terracotta is used for underground burial, black soil pipe fittings are UV-stabilized. This means they can be installed on the exterior of a building without warping, fading, or becoming brittle due to sun exposure. Our coupler ensures your drainage system remains structurally sound and aesthetically consistent with your guttering and downpipes.
Forget the mess of solvent cements. This 110mm push-fit coupler features a “ring seal” system. The internal rubber gaskets are designed to allow for thermal expansion and contraction, preventing the joints from cracking as temperatures change.
Eco Heat Shop Tip: Always use a silicone-based lubricant on the pipe ends to ensure the seal stays seated correctly during insertion.
