Abstract
The method of forming a tube fitting assembly is disclosed in a fitting having a first bore through a portion of the fitting and a second bore larger than the first bore and concentric with and through a portion of the first bore. A tubing having a diameter substantially equal to the first bore is engaged against an inside surface of the fitting defined by the end of the first bore. Relative movement between the fitting and the tube deforms the tubing wall to engage the first and second bores and to form an annular bead of the tubing wall outside of the fitting assembly. The bead is swaged into engagement with an outside surface of the fitting surrounding the second bore. The foregoing is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
