3 in End-of-Pipe Plug

The Cherne 270237 is a new end-of-pipe plug designed to seal 3 in pipes from the inside. Its gripper mechanism expands against the pipe wall when the wing nut is tightened. The seal operates at the pipe end and accepts an internal diameter range of 2.8 in to 3.1 in. The assembly stands 2.5 in tall overall.

Suits temporary pipe sealing, not permanent closure

This plug suits maintenance crews and contractors who need a reusable, tool-free seal for pressure testing or flow isolation. The wing nut allows hand installation and removal without spanners. It is not for permanent installations where a fixed mechanical joint or solvent-weld cap is required. Buyers needing a bypass port or a padlockable security feature should look elsewhere.

17 psi air / 40 ft water back-pressure rating

The single specification that decides fit is the maximum back-pressure rating: 17 psi for air and 40 ft of head for water. If the test or isolation pressure exceeds these values the plug will not hold. The zinc wing nut and ABS plate deliver the stated rating within the 2.8 in to 3.1 in inside-diameter window.
