Patent ID: 7740283

Claim:
A female fitting component for use in a tube fitting in which there are only two separate components prior to assembly, wherein the only two separate components consist of the female fitting component and an externally threaded male component, wherein the tube fitting grips and seals a tube when the fitting is tightened, wherein the female fitting component comprises: a female nut having internal female threads; a tube gripping device attached with the female nut; wherein assembling of the female fitting component with the male fitting component separates the tube gripping device from the female nut; wherein the tube gripping device is configured such that during pull-up a forward end of the tube gripping device produces a tube bite into an outer surface of the tube, and said tube gripping device deforms so that a portion of an interior wall of said tube gripping device that is adjacent to the tube bite isolates the tube bite from vibration.
