ABSTRACT:
A coupling assembly for leak proof connection of the ends of two lengths of pipe or tubing. One end of a first pipe is coupled to a coupling box which is connected to or integrally formed on the end of a second pipe. The coupling box has threads for engaging a nut for securing the coupling. The coupling box has a bore for receiving the end of the first pipe. The end of the first pipe has an outer tapered surface for engaging an inner tapered surface of the coupling box to form a metal to metal seal between the first pipe and the coupling box. The bore also contains an engager for coupling the nut to the first pipe. The engager includes a split ring which has a longitudinal slot. The split ring has internal circumferential projections or gripping teeth which are aligned with external circumferential projections or gripping teeth on the end of the first pipe. As the nut is tightened, the split ring is compressed so that the gripping teeth of the split ring are brought into engagement with the gripping teeth or the first pipe. The split ring and the first pipe are then moved relative to the coupling box so that the outer tapered surface at the end of the pipe is forced into metal to metal sealing contact with the inner tapered surface within the bore of the coupling box.
