    Compression

    Compression fittings consist of a nut and a ring that, when tightened, compress the fitting onto the pipe, creating a watertight seal. These fittings do not require soldering, making them ideal for situations where disassembly and reassembly may be necessary.

    This range of fittings can be used with a variety of materials including light gauge plain and chrome plated copper tube, stainless steel, carbon steel tube, PEX, PB and polyethylene pipe. The fittings are WRAS approved to EN1254 (BS864) and come with a full manufacturer’s guarantee.
