A threaded plug having a tapered configuration from an outer to an inner end thereof is threadably receivable in the sealing ring whereby the sealing ring is expanded and engages the opening in sealing relation. The plug includes a multi-sided boss fixedly attached to and extending from its outer end. The sealing ring engages the opening when the plug is received in the bore thereof in a frictional engagement whereby the sealing ring resists rotation and axial sliding within the opening as the plug is axially advanced into the bore.
