4 in Mechanical Pipe Plug

The Cherne 270245 is a mechanical pipe plug designed for 4 in pipe sizes. It fits inside diameters ranging from 3.8 in to 4.06 in. The plug uses ABS plastic and rubber components with a zinc handle for manual operation. It is intended for temporary pipe sealing and testing applications.

Suited for pressure testing and line blocking

This plug suits plumbers and contractors performing low-pressure air or water tests on 4 in lines. It handles up to 17 psi air pressure and 40 ft of water head. Buyers needing a bypass connection for flow-through testing or a padlockable security feature should look at alternative designs. The plug seals at the pipe end only.

Capacity and headroom

The unit comfortably seals pipes within the 3.8 in to 4.06 in inside diameter range. It withstands 17 psi of air back pressure and 40 ft of water head during testing. The 2.5 in overall height allows insertion into standard fittings. It runs out of sealing capability beyond the stated diameter limits or if pressure ratings are exceeded.
