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.
