ABSTRACT:
A tubing termination comprises a termination portion adapted to make a fluid connection and a tube attachment portion, adapted to receive a tube and to be crimped or swaged. The tube attachment portion comprises a retention mechanism that is adapted to be manipulated during crimping or swaging to bite the tube so as to lock the tube attachment portion relative to the tube. This retention mechanism may take the form of a deformable bite ring, a deflectable c-insert, irregularities defined on an inner surface of the tube attachment portion, and/or the like. The tube attachment portion also may include a resilient sealing mechanism adapted to provide a seal between the tube and the tube attachment portion, and thereby a fluid-tight connection between the tube and the termination portion.
