Cherne 1-1/2-in dia ABS Test Ball Plug Fitting

The inflatable test plug is ideal for testing drain, vent, and waste plumbing systems at pressures up to 13 PSI or 30-ft of head pressure. Made of natural rubber, the plug easily fits through test tees, sanitary tees, floor drains and other hard to access pipe openings. The inflatable test plug will work in virtually any type of pipe. And unlike mechanical plugs, it will also seal out of round pipe. Each plug comes with a chain and ring handle to prevent the plug from being drawn into the pipe during tests.
