Plumbing Fittings

The fittings that connect, divert, adapt, and terminate pipework are the building blocks of any plumbing installation. At the DIY Hardware Store, our plumbing fittings range covers the compression fittings, push-fit connectors, washing machine and appliance hose connections, and the miscellaneous fittings used in domestic hot and cold water, heating, and waste systems.

The range spans compression fittings for copper pipe (elbows, tees, straight couplings, stop ends), speedfit push-fit plastic fittings for faster installation in compatible pipe systems, washing machine and dishwasher fittings including inlet hoses, outlet hoses, and double-check valves, brass compression nuts for connection to valve bodies and appliance connections, and the adaptors and reducers needed where different pipe materials or diameters need to be connected.

Available at the DIY Hardware Store in the standard UK domestic plumbing sizes - 15mm, 22mm, and 28mm for pressurised systems; 32mm and 40mm for waste - with products from proven manufacturers for reliable, leak-free performance.
