Test drain, vent and waste plumbing systems with this inflatable test plug. It works with systems with pressures up to 13 PSI or 30 ft. of head pressure. Featuring natural rubber construction, the plug is easy to fit through test tees, sanitary tees, floor drains and other hard-to-access pipe openings. It will work with most pipe types. It will also seal out of round pipes, unlike its other mechanical counterparts. Each inflatable plug comes with a chain and ring handle to prevent it from being drawn into the pipe during tests. Color: Black.
