How Super Speedfit Fittings Work
To make a connection, the tube is simply pushed in by hand; the unique patented John Guest collet locking system then holds the tubing firmly in place without deforming it or restricting flow.
To disconnect, ensure that the system is depressurized, push the collet square against the fitting. With the collet held in this position the tube can be removed.
