An outer surface includes a plurality of steps corresponding with different pipe sizes for engagement within the pipe. The outer surface is threaded or includes a locking mechanism which moves a portion of the two engageable plug halves into physical engagement with threads of the pipe. The locking mechanism can include locking pins at each of the outer steps, and which are extended outward by a manual push button upon the plug being placed in a pipe.
