  • Tube fitting assembly
    Patent number: 9841128
    Abstract: A tube fitting for sealing an end of a tube uses a notch formed in the exterior surface of the tube as a sealing seat. An internally threaded body is configured to receive an externally threaded end of a nut, while the body and the nut are mounted in a surrounding relationship to the tube end. A ferrule mounted between the nut and the tube is forced to plastically deform and move into the notch to thereby seal the tube end.
    Type: Grant

  • Tube-fitting-assembly ferrule
    Patent number: 9695963
    Abstract: A tube-fitting-assembly ferrule apparatus and method to secure connections between tubing sections against high pressure, vibration, pulsation, and hammering, by providing a tube-fitting-assembly ferrule which elastically deforms in use, securing the primary circumferential point seal with a shock-absorbing and shape-retaining force.
