Paragon Underground Drainage Double Socket Equal Junction 87.5°

This 110mm equal junction takes a branch into the main at 87.5°, pairing push-fit ring seal sockets on the inlet and branch with a spigot outlet. The two sockets receive plain ended pipe or spigot fittings. The chamfered spigot outlet inserts directly into the socket of the next pipe or fitting downstream, such as a single socket pipe or a bend.

The spigot outlet lets the junction be coupled straight into the following fitting without a short connecting length. This keeps the layout compact where a near square-on branch must join just before a change of direction. Inside, the branch meets the main through a curved profile that turns incoming flow towards the direction of the main run. The 2.5° short of square angle leaves the branch with a slight fall into the main.

• 87.5° branch: Connects a side drain almost square on to the main where a 45° branch will not fit.
• Spigot outlet: The outlet inserts directly into the socket of the next pipe or fitting, with no short pipe length needed.
• Chamfered spigot: The spigot end is moulded with a chamfer, ready for insertion into a ring seal socket.
• Curved branch entry: The curved internal profile guides incoming flow into the direction of the main run.
• Equal junction: The branch matches the 110mm main, so the same pipe size is used on all three legs.
• Push-fit ring seal: The inlet and branch sockets carry ring seals for push-fit jointing, with no solvent cement required.
• Recognised standard: Manufactured in accordance with BS EN 1401-1.
• Made in Great Britain: Manufactured in Great Britain by Polypipe, and finished in terracotta.
