Abstract:
1. An axially swaged fitting for joining to a tube, the fitting comprising: a sleeve comprising as inner material and a swaging ring comprising an outer material and sliding over the sleeve when forced in an axial direction to deform the sleeve and said tube to thereby create a swaged joint; a first mating metal layer located between the sleeve and the swaging ring, the first mating metal layer being on one of the sleeve and the swaging ring and comprising a relatively hard metal; and a second mating metal layer located between the sleeve and the swaging ring, the second mating metal layer being on the other of the sleeve and swaging ring and comprising a relatively soft metal, so that engagement of the first mating metal layer and the second mating metal layer deforms the soft metal during a swaging of the sleeve and the swaging ring and forms a continuous metal-to-metal contact between the swaging ring and the sleeve, creating a constant electrical path between the swaging ring and the sleeve.
