An apparatus and process by which a leak-proof connection with a polymeric tube is described herein. Particular embodiments of the present invention include a leak-proof connection fitting inserted into a bore of a overmolded attachment piece wherein the overmolded attachment piece is overmolded onto the polymeric tube. The leak-proof connection fitting includes multiple surfaces in various configurations. The multiple surfaces include barb(s), raised surface(s), reduced surface(s), and channel(s). O-rings may be further added to the leak-proof connection fitting. In some embodiments, the overmolded attachment piece or the tube itself is secured to the fitting by shape memory.

An expansion tool includes a working element configured to expand an end of a tube. The working element includes a plurality of jaws movable between a closed position and an expanded position. The expansion tool also includes first mandrel with a first contact surface and a second mandrel coupled to the first mandrel. The second mandrel has a second contact surface. The first mandrel and the second mandrel are movable together relative to the jaws between a retracted position and an extended position. The first contact surface and the second contact surface are engageable with the jaws to move the jaws from the closed position toward the expanded position in response to movement of the first mandrel and the second mandrel from the retracted position toward the extended position.

An expansion tool includes a housing, a motor supported within the housing, a mandrel, and a drive mechanism configured to convert a rotational input from the motor into translational movement of the mandrel. The drive mechanism includes a cam and a drive shaft coupled to the cam. The expansion tool further includes a frame including a hub and a neck extending from the hub and having an opening. A working element is coupled to the neck and has a plurality of jaws movable from a closed position toward an expanded position in response to movement of the mandrel from a retracted position toward an extended position. The mandrel extends through the opening to engage the jaws, and the drive shaft is rotatably supported by the hub.
