Abstract
A coupling assembly comprising a coupling having a pipe stop protruding from its inner surface, an o-ring groove between the pipe stop and the receiving end of the coupling, a spline insertion hole, and a coupling groove portion for receipt of a spline rod. The coupling assembly also includes a spacer ring and a pipe having a bevel portion at the insertion end of the pipe and a pipe groove portion on the flat, cylindrical surface of the pipe, wherein the tip of the insertion end of the pipe contacts the spacer ring upon insertion of the insertion end of the pipe into the receiving end of the coupling to position the pipe and align the first spline groove portion on the inner diameter of the coupling with the second spline groove portion on the outer diameter of the pipe to form a spline groove for receipt of a spline rod to lock the coupling and the pipe in place.
