    How To Use These Great Push To Connect Fittings...

    To make a connection, the tube is simply pushed in by hand; the unique collet locking system then holds the tube firmly in place without deforming the tube or restricting flow.
    Start by pushing the tube into the fitting and up to the tube stop.
    After the tube has been inserted, pull on the tube to check that it is secure.
    It's a good idea to use a simple tube cutter for a square cut and to remove burrs and any sharp edges.
    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.
