ABSTRACT:
The present invention provides an apparatus for making a tube connection. The apparatus comprises a sleeve having an interior surface adapted for receiving a tube section therein. The sleeve further has an exterior surface having a locking mechanism disposed on an outer portion thereon, such outer portion has a first end and a second end. There is an upwardly inclined surface extending from such second end of such outer portion of the sleeve. Extending inwardly from the upwardly inclined surface is a generally cylindrical sleeve wall that is substantially parallel to a longitudinal axis extending through the sleeve from one end to another. There is further a stop flange disposed on a center portion of such sleeve extending radially outwardly from such center portion of such sleeve, such stop flange is disposed substantially adjacent such generally cylindrical sleeve wall. Such apparatus further includes a driver mechanism for engaging and deforming the sleeve and concurrently such tube section engaged within the sleeve. The driver mechanism has at least two cylindrical sections for engaging the exterior surface of the sleeve. A first end of the driver contacts such stop flange of the center portion of the sleeve and a second end engages the locking mechanism of the outer portion of the sleeve. Such sleeve also includes an anti-torque surface treatment on the inner surface of the ends to resist torsion of the tube.
