Description
The Wavin Osma 110mm 87.5 Degree Equal Junction (Single Socket) is a versatile underground drainage fitting designed for connecting three 110mm pipes at a T-shaped angle. With an accurate 87.5-degree branch, it’s ideal for linking lateral pipe runs into a main line while maintaining optimal flow performance.
This version features one push-fit socket with Wavin’s integrated RootSeal technology, which includes a co-injected ring seal containing a built-in inhibitor to block tree root ingress. The remaining two outlets are plain-ended spigots, suitable for direct insertion into compatible fittings or couplers.
Manufactured from high-strength PVC-U, the junction is lightweight, corrosion-resistant and built to perform in tough below-ground conditions. The combination of push-fit and spigot ends provides flexible installation options across both new and existing systems.
The Wavin Osma 110mm 87.5 Degree Equal Junction is part of the fully compatible OsmaDrain system and meets the specifications of BS EN 1401-1. It is suitable for foul and surface water drainage applications across residential, commercial, and civil engineering environments.
