The Pushfit Waste Straight Connector 40mm (also known as a straight coupling or double socket connector) is a linear joining fitting designed to connect two lengths of 40mm waste pipe in a continuous, straight run. Manufactured from high-impact polypropylene, this fitting provides a secure, aligned inline connection for domestic drainage systems.
 
Equipped with factory-installed elastomeric rubber lip seals in both sockets, the connector enables a fast, dry, push-fit joint without requiring solvent weld cement or special tools. The internal center stop ensures equal insertion depth for both pipe ends, while the push-fit mechanism allows for thermal expansion and contraction along the pipe run, preventing structural strain and leakage over time.
 
Ideal for extending 40mm waste pipe runs for kitchen sinks, washing machine standpipes, and bath drainage, this straight connector is compatible with standard 40mm push-fit plastic waste systems. Built to withstand continuous hot water discharge and common household detergents, it offers plumbers and DIYers a reliable, reusable, and leak-proof jointing solution.
 
Pushfit Waste systems are highly adaptable and manufactured to BS EN 1329:2000. They are fully compatible with other systems.
