Create secure, leak-free intersections in your underground drainage systems with the Brett Martin 110mm 45° Triple Socket Branch (B4091).Also widely referred to as a "Y junction" or "triple socket drainage branch," this heavy-duty fitting allows you to seamlessly connect three standard 110mm drainage runs at a precise 45-degree angle to optimize wastewater flow.

Key Features & Benefits

• Optimized Flow Dynamics: The 45° swept configuration allows foul water or surface runoff to enter main lines smoothly, minimizing the risk of turbulence and solid build-ups.
• Captive Seal Technology: All three sockets come fitted with non-dislodgeable, co-moulded seals to ensure 100% watertight integrity over an extended operational life.
• High Impact Resistance: Constructed from premium PVC-U to withstand physical impacts during backfilling and heavy-duty ground conditions.
• Certified Quality Assured: Kitemarked to BS EN 1401-1 or BS EN 13476-2 and manufactured under an ISO 9001:2015 certified quality framework.
• Universal Compatibility: Seamlessly integrates with standard 110mm solid-wall PVC-U underground drainage pipes.

Manufactured in the UK from robust PVC-U, this branch is engineered to withstand the demanding environments of both domestic and commercial underground drainage systems.It handles structural soil loading, minor ground movement, and temperature fluctuations without losing its physical integrity.

Designed for Effortless Installation

The B4091 features Brett Martin’s innovative captive lip and compression seals across all three sockets.Unlike traditional drainage fittings where seals can dislodge or bunch up during jointing, these rings stay completely locked in place.This ensures a swift, reliable "push-fit" connection that forms a permanent watertight barrier against root penetration and wastewater
