Design:

When tubing (1) is inserted into the fitting, it first passes through the gripping teeth (2).

Just beyond the gripping teeth is the o-ring (3) which provides the leak proof seal against the OD of the tube.

The gripping teeth grab the tube, which expands the insert. Pulling back on the tube only tightens the grip as the insert moves onto the camming surface (4).

Pressure through the tube also serves to tighten the grip.

The tube bottoms against a positive tube stop (5) in a cavity providing tube support to prevent leakage.
