Abstract
A coupling assembly includes a pair of glands having ends that seal on opposite faces of a seal member. A coupling nut assembly cooperates with the glands to urge the ends against the seal member. A torque suppression assembly is mounted on a groove of the gland to limit rotational forces from the coupling nut assembly to the gland. The torque suppression assembly includes a thrust member that engages the coupling nut assembly and a bearing member that transfers axial make-up forces from the thrust member to the gland and rotates relative to the thrust member to reduce the torque transfer.
