Patent number: 7207605Abstract: Coupling components which prevent relative rotation between tubular members when break away torque forces are applied to the tubular members. In one embodiment, the invention is a locking ring for preventing relative axial rotation between two generally tubular members. The ring is shaped to receive a sealing gasket and has two side faces wherein each side face is shaped to frictionally engage one of the tubular members to thereby prevent relative axial rotation between the tubular members. The invention is also directed to a coupling including a locking ring. The tubular members are generally coaxially arranged such that the sealing faces face each other. The coupling comprises a sealing gasket captured between the sealing beads for sealing the coupling, wherein the frictional surfaces engage the sealing gasket to prevent relative rotation between the tubular members.Type: GrantFiled: August 11, 2003Date of Patent: April 24, 2007Assignee: Swagelok CompanyInventors: Benjamin J. Olechnowicz, Gerald A. Babuder, Timothy A. Barney, Ronald K. Fisher

Patent number: 5947533Abstract: A pipe joint assembly comprises a pair of cylindrical pipe ends of the same internal diameter in axially contiguous aligned relationship. Connecting flanges extend radially outward of each of the pipe end and have opposed faces defining a circumferentially continuous packing groove including a first axially narrow portion opening to the cylindrical interior of the pipe ends and a second axially wider portion radially outward of the first portion. An elastomeric gasket positioned in the packing groove. The gasket is sized and dimensioned to completely fill the first axially narrow portion and extend to within the second portion. The radial inner extent of the gasket provides a smooth continuation of the cylindrical interior surfaces of said pipe ends when the flange faces are at their limit of movement toward one another.Type: GrantFiled: August 2, 1996Date of Patent: September 7, 1999Inventors: Ronald K.
