Floplast U/G Equal Junctions – Double Socket 45°

The 110mm 45° Equal Junction is a vital component for expanding or merging underground drainage networks. Unlike a standard 90-degree T-junction, the 45-degree “swept” angle of this Y-junction is specifically designed to introduce water from a branch line into the main run with minimal turbulence. This promotes a superior flow rate and significantly reduces the risk of sediment build-up or blockages at the junction point, making it the preferred choice for both foul and surface water systems. Constructed from durable, high-impact terracotta uPVC, this junction is built to withstand the rigours of below-ground burial, including ground movement and exposure to soil chemicals. The “Double Socket” configuration means the main run features two push-fit sockets, while the 45° branch is typically a plain end (spigot), allowing for flexible assembly. Each socket contains a pre-fitted captive rubber ring seal that creates a permanent, leak-proof joint. This fitting is fully compliant with BS EN 1401-1 standards, ensuring it integrates seamlessly with all standard British 110mm pipework. Optimised 45° Branch: The “Y” shape ensures a smooth transition for water and waste, maintaining high-velocity flow and preventing blockages. Double Socket Design: Features push-fit sockets on the main line for quick, secure connection of plain-ended 110mm pipes without additional couplers. Captive Seal Technology: Includes pre-fitted rubber gaskets that stay securely in place during installation, ensuring a 100% watertight seal. High Durability: Manufactured from robust uPVC that is resistant to corrosion, chemicals, and the high-impact stresses of underground use. Industry Standard: Fully compatible with all 110mm (4-inch) underground drainage pipes and fittings, suitable for domestic and commercial applications.
