Description
The Wavin Osma 110mm 87.5 Degree Equal Junction is a reliable underground drainage fitting designed to connect three 110mm pipes at 87.5-degree angles. This T-junction configuration is typically used for creating branch connections in foul or surface water drainage systems where efficient flow and layout flexibility are required.
This version includes double socket connections, with push-fit seals on all three inlets, allowing for fast and secure connections between plain-ended 110mm pipes. Each socket features Wavin’s advanced RootSeal technology, a co-injected ring seal that includes a built-in inhibitor to help block tree root ingress — protecting the joint and system over time.
Manufactured from tough and lightweight PVC-U, the junction is corrosion-resistant and impact-resistant, making it suitable for a wide range of underground conditions. The push-fit design speeds up installation, eliminates the need for solvent welding, and makes the fitting ideal for both new construction and refurbishment projects.
The Wavin Osma 110mm 87.5 Degree Equal Junction forms part of the Wavin OsmaDrain system and complies with BS EN 1401-1, ensuring full compatibility with all other 110mm fittings and pipes in the range.
