Abstract
A connector means which provides a fluid-tight seal, but with relative rotation of a pair of body members of a hydraulic line or device. Cylindrical extensions on both the body members, which interfit in assembly, have circumferential grooves facing one another and receive ball bearing members in the circumferential chamber provided by the grooves; and the arrangement is such that the bearing members act to block axial withdrawal of the body members from a tight sealing engagement with an O-ring which assures fluid-tightness of the joint even though the body members are relatively rotatable.
