To Release Tubing
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 necessary to cut the tubing, use a plastic tubing
cutter or sharp razor knife. Make a clean square cut.
