Abstract
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. A sleeve having an outwardly extending projection receives the tubing with the projection located within the second bore. Relative movement between the fitting and the tubing radially expands the tubing wall to engage the first and second bores and deforms the sleeve projection outwardly from the tubing to engage the second bore by action of the radial expansion of the tubing wall. 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.
