Abstract
The invention relates to a coupling assembly for connecting two members. The coupling assembly prevents excessive radial movement, scrubbing of the coupling members, and leakage of fluid being transferred through the coupling. The coupling assembly includes a tube end having a pair of spaced apart annular beads defining a groove for a resilient seal ring seated in the groove and the other member defined a bore for receiving the tube end. A guide ring substantially centers the tube in the bore whereupon a clamping assembly releasable connected to the tube is clamped to the other member securing the tube in the centered position while permitting limited axial movement of the tube.
