Sealing or testing a drain line, this rubber trap plug is the expandable stopper that blocks a trap, cleanout, or drain opening to hold back water for a pressure test or to seal off a line during service. Tightening the wing nut compresses the rubber so it expands against the pipe wall for a tight, removable seal that holds test water or keeps sewer gas out of an open line. It pulls out just as easily when the work is done, leaving the line clear. A handy item for drain testing and temporary sealing, it is a low-cost staple for a plumber or drain tech servicing traps and cleanouts.
