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.
