ABSTRACT:
A sealing device which may be used as either a test plug or a sealing plug for closing an opening in a wall of a fitting characterized by a bolt-shaped pressure component having a disk-shaped rim at one end and threads at the other end for threadably receiving a thrust nut. An elastic sealing member and a thrust washer are arranged between the rim and the thrust nut so that the sealing member will be radially expanded into engagement with the periphery of the opening in a wall of the member or fitting as the nut is threaded onto the pressure component.
