To Release Tubing
‘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
cause is usually defective tubing.
To fix leaks:
• Relieve pressure.
• Release tubing.
• Cut off at least 3/8” (9.5 mm) from end.
• Reattach tubing.
• Confirm connection is leak free.
