Slip Coupler (Double Socket) for 110mm Plastic Terracotta Underground Drainage
Manufactured to BS EN 1401-1!
Double socketed coupling for joining of 110mm plain ended drainage pipes or fittings. No central stop, so can be slipped along pipe, which makes it ideal for replacing sections of pipe and fitting in tight space. Features fixed EPDM rubber seals to both ends. Pipe should be chamfered and lubricated with silicone grease or spray prior to fitting, to ensure the best seal. Insert pipe to central stop and pull back 10mm to provide room for ground movement.
Part of our range of durable and impact resistant fittings for 110mm plastic PVC-u underground drainage pipes, the most common residential system. These lightweight, easy-fit parts are compatible with all systems manufactured to BS EN 1401 or BS EN 13476-2.
The range of pipe and bend fittings are available with pre-chamfered plain or socketed ends, which feature a ring seal for easy and secure connection to different parts of the system. These fittings can be used in conjunction with new or existing inspection chambers, or soakaway crates, to complete the underground drainage system.
