Underground uPVC 160mm Double Socket Coupler with Centre Stop
The Underground uPVC 110mm Double Socket Coupler with Centre Stop is a reliable and sturdy straight-connection fitting designed to join two lengths of below-ground drainage pipe securely. Manufactured from tough, high-impact unplasticized polyvinyl chloride, this coupler is engineered to withstand heavy external soil loads, ground movement, and corrosive subterranean environments, ensuring long-term structural integrity and dependable performance.
Featuring an internal centre stop, the fitting ensures that both inserted pipe spigots stop precisely at the halfway point, preventing over-insertion and maintaining a balanced, uniform overlap. Each end is equipped with factory-fitted captive seal rings that deliver an immediate, watertight, and root-resistant joint right out of the box, eliminating the need for specialist welding or adhesives.
Designed for quick and straightforward push-fit installation in trenches, the coupler allows installers to extend pipe runs or make repairs efficiently. Smooth internal transitions prevent flow restriction and sediment buildup across the joint. Whether you are extending an existing drainage run or completing essential repairs, this double socket coupler delivers professional-grade alignment, durability, and leak-free performance underground.
