Cherne Gripper Mechanical Plugs are ideal for plumbing system tests. They're easy to install with an extra-large wing nut. The inside of the pipe seals inside pipe as far as needed. Plugs are made with glass-reinforced ABS plastic. End-of-pipe seals only at the end of a pipe, preventing plug from falling into stack.
