‘Push-In’ Tubing Connector (John Guest® Fitting)

This product is outfitted with user friendly “Push In” connectors. Proper use of the connectors is shown in the diagrams. It is most important that the tubing selected for use with these connectors be of high quality, exact size and roundness, and with no surface nicks or scratches. If it is neces- sary to cut the tubing, use a plastic tubing cutter or sharp razor knife. Make a clean square cut. Should a leak occur at a ‘Push In’ connector, the
