The 22mm x 15mm reducing coupler is a fully demountable and reusable push-fit fitting for hot and cold plumbing and radiator central heating systems. It also combines with polybutylene pipe to create a flexible plumbing system. The radial sealing force provides a more secure watertight seal and the 3-pin protection feature ensures fittings are not accidentally demounted when installing through joists, floors or walls.
