A pipe swivel joint comprises a female conduit element and a male conduit element rotatably engaging the female conduit element. A removable plug within the female conduit element maintains a main seal in proper position for bridging a clearance between the female and male conduit elements. The plug is easily removed once the main seal is to be replaced, and is installed back in place once the main seal has been replaced, thereby avoiding dismantling of the swivel joint.
