ABSTRACT:
Swivel connector apparatus for use in connecting lines together which carry a pressurized fluid and which require relative rotation therebetween is disclosed which includes an outer body having a bore formed axially therein which extends entirely therethrough. An inner body is configured for an interfitting relationship between a first portion thereof and the bore of the outer body which includes three bore portions. The inner body includes a bore formed axially therein which extends entirely therethrough. The first portion of the inner body is provided with a predetermined number of annular cavities on the outer surface at predetermined locations. Sealing means and radial bearing means are positioned in predetermined annular cavities of the first portion of the inner body and are in engagement with the first portion of the inner body and the bore of the outer body. A retaining nut and a one-piece combined radial and axial bearing are positioned on the first portion of the inner body at a predetermined location and are maintained at that location by retaining means. The combined radial and axial bearing is in engagement with the inner body, the outer body and the retaining nut. Threads in the retaining nut cooperate with threads on the outer body to maintain the inner and outer bodies in operative rotatable relationship.
