NOTE: To remove a piece of tubing, remove the blue clip and press down on the collet where the
tubing enters the fitting. While the collet is depressed, remove the tubing from the fitting.
NOTE: We recommend cutting the tubing with a razor blade or something similar, so the tubing
is not pinched. If the tubing is pinched, it will not seal properly. All tubing connections will have a
"double push" into the connectors. You should feel a two-step insert to verify the tubing is inserted
completely into the connectors.

Buddie Fit press fittings before installing
the tubing (left page).
