<p>A tubular crimp connector is provided for attaching a valve assembly or the like to a metal pipe, a fluid tight mechanically secure manner. The connector includes a tubular section made of a metal alloy defining an axial bore size d to receive the pipe with an interior circumferential sealing surface and a plurality of integrally formed annularly spaced apart teeth oriented between the sealing surface and the connector distal end. The wall thickness of the connector in the region of the spaced apart teeth is sufficiently thin to be radially, plastically, permanently deformable by a crimping tool. It is sufficiently thick to provide a mechanically secure interconnection between the tubular connector and the metal pipe without requiring a reinforcing ferrule. The method of forming is provided in which a preform is hot forged and finish machined to the final shape.</p> |
