A swivel connector between a flexible hose and a nozzle has a reduced portion of a first body secured to the nozzle and an enlarged portion of a second body secured to the hose with the first and second bodies, which have an enlarged portion of the first body overlapping a reduced portion of the second body, providing aligned passages therethrough to provide communication between the hose and the nozzle. A plastic thrust bearing is disposed between a metallic ring secured by set screws to the enlarged portion of the first body and a metallic ring mounted by flats on the ring cooperating with flats on the reduced portion of the second body so that each of the rings rotates with the body to which it is connected. The thrust bearing has a first face, which is perpendicular to the axis or centerline of the aligned passages, engage a substantially parallel face on the metallic ring secured to the first body and a second face, which is substantially parallel to the first face, engage a substantially parallel face on the metallic ring secured to the second body. Thus, all rotation occurs between one of the faces of the thrust bearing and the face on one of the metallic rings. A pair of plastic radial bearings is disposed between the enlarged portion of the first body and the reduced portion of the second body to provide bending support thereto. One of the radial bearings is disposed adjacent the metallic ring secured to the first body while the other radial bearing is disposed adjacent a seal ring which is spaced from the metallic ring secured to the second body and provides the seal between the first and second bodies.
