Push-fit fitting

A push-fit fitting is installed without tools: the pipe, cut square, is pushed into the fitting, where a toothed collet grips it and an O-ring provides the seal. To release it, push the collet against the fitting and pull out the pipe.

The John Guest Speedfit range covers pipe diameters from 4 to 28 mm:

single and double unions, equal or unequal, tees, equal elbows, Y connectors, bends;
reducers and plugs;
male and female threaded adaptors, BSP parallel or BSPT taper, in plastic or brass, including DZR brass;
locking clips and pipe inserts for plastic pipe.

According to John Guest, metric Speedfit fittings can be used on PE-X or polybutylene pipe, with an insert, and on copper pipe. John Guest PEX pipes are in the Pipe family. The range also includes RPM brass push-fit fittings (20 bar) and Kronos Push (PN50).

How to choose: the outside diameter of the pipe, the thread of the equipment to connect, then the working pressure and temperature given by the manufacturer for each item.

Brands: John Guest and RPM.
