The Pushfit Waste Socket Plug Black 40mm (also referred to as a blanking plug or end plug) is a protective fitting designed to cap off open 40mm push-fit waste sockets or branch outlets. Manufactured from high-impact, UV-stabilized black polypropylene, this plug provides an airtight and watertight seal to close unused ports, seal off temporary pipework, or blank off redundant junctions in domestic drainage installations.
 
Equipped with a precision spigot profile and a factory-fitted elastomeric rubber lip seal, the plug pushes directly into any standard 40mm push-fit socket or fitting without requiring solvent weld cement or special tools. Its smooth outer face features a raised lip or grip ring, allowing quick, tool-free removal when accessing the socket for future system expansions or rodding.
 
Ideal for sealing off unused appliance branch connections, kitchen waste extensions, and temporary drainage stubs, this plug prevents sewer gas, bad odors, and leaks from escaping into living spaces. Resistant to hot water discharge and household cleaning chemicals, the 40mm black socket plug offers plumbers and home improvers a durable, reusable blanking solution.
Pushfit Waste systems are highly adaptable and manufactured to BS EN 1329:2000. They are fully compatible with other systems.
