Abstract: The invention pertains to high pressure conduit swivel joints capable of conducting fluid pressures of 6,000 psi wherein the associated conduit members of the joint are permitted angular deflection and relative rotational movement. An elastomer assembly is interposed between the conduit associated members of the joint permitting limited relative rotational movement solely due to elastic deformation, and greater rotative movement produces bearing supported rotation of the members. A tubular sleeve is mounted upon a body, and a retainer attached to the body maintains the sleeve thereon, and the elastomer assembly is compressed by the retainer which controls the torque requirements for producing bearing rotative support of the members, such bearing supported rotation occuring at greater torque conditions than that necessary to produce limited member rotation due to elastomer deformation.

Abstract: An elastomeric gasket for use with pipe coupled in end-to-end relationship wherein the coupling employs a split collar received within grooves within the pipe's circumference, the gasket being of a transverse cross section including deflectable lateral leg portions and a deformable central region. The leg portions include sealing surfaces engaging the pipe circumference, and the gasket configuration produces annular cavities between the central region and the leg portions in the normal relaxed gasket condition to permit the desired gasket deformation when compressed. The configuration and relationships of opposed adjacent surfaces of the leg portions and central region are such that when the gasket is under compression the cavities existing in the gasket when in the relaxed condition are totally eliminated by engaging gasket surfaces, and no voids exist in which foreign matter, water or fluids may be trapped.
