TO CONNECT TUBE:
Cut plastic as squarely as possible. Insert tube
into fitting until friction is felt as tube slides past
the O-ring. Using a slight twisting motion while
inserting the tube is often helpful. After this initial
friction is felt, continue to push in the tube until
TO DISCONNECT TUBE:
With thumb and forefinger, hold down the top
of the insert against the fitting body and then,
with the other hand, pull out the tubing.
No tools are needed.
