摘要： A tube fitting assembly is disclosed comprising a fitting having a first orifice through a portion of the fitting and a second orifice larger than the first orifice and coaxial with and through a portion of the first orifice. The second orifice extends from an outside surface of the fitting. One of the first and second orifices contains a shoulder defining areas of different cross-sectional areas within that orifice. The shoulder includes a shoulder surface facing axially inwardly relative to the outside surface of the fitting. A tubing having a diameter substantially equal to the first orifice occupies the first and second orifices with a first deformed portion formed from a radially expanded tubing wall engaging the other of the first and second orifices. The tubing has a second deformed portion from first and second parts of the tubing inside wall axially contracted and folded into engagement with each other to provide radial expansion of the tubing wall engage the shoulder surface to seal the tubing to the fitting and preventing axial separation of the tubing from the fitting. The foregoing is merely a resume of one general application, is not a complete discussion of all principles of operation of applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

摘要： A tube fitting assembly is disclosed comprising 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 engages 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.
