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.
