Compression Waste Fittings

Waste pipe connections under sinks, basins, and baths don't need a blowtorch - they use compression waste fittings that seal by mechanical compression without adhesive, heat, or specialist tools. At the DIY Hardware Store, our compression waste fittings range covers the traps, waste couplings, bends, and tee pieces for 32mm and 40mm waste pipe used in domestic bathroom and kitchen plumbing.

Compression waste fittings use a rubber seal and a threaded compression nut to create a watertight joint around the pipe. Joints can be disassembled for clearing blockages or replacing components without cutting the pipe, the assembly process is forgiving, and no curing time is needed before putting the system into service.

They're the standard fitting for below-sink waste plumbing, bath traps, and the waste runs between appliances and soil pipe connections in domestic settings. Available in white and grey to match the most common waste pipe colours.
