Cherne 269875 1 in Pipe Plug Trap

Pipe Plug for 1 in Pipes

The Cherne 269875 pipe plug seals 1 in pipes with an inside diameter between 0.86 in and 1.02 in. It uses a wing nut mechanism to expand the sealing element against the pipe wall. The unit stands 2.18 in tall and is built from galvanized steel plates and handle. No water fill port or hose is included with this model.

For Temporary Line Blocking and Testing

This plug suits maintenance crews and plumbers who need to isolate a 1 in line for pressure testing or repair work. It holds up to 40 psi of air pressure and 92 ft of water head. Buyers needing a bypass connection to flow fluid through the plug should look elsewhere. The design also lacks a padlock shackle, so it does not support lockout-tagout security requirements.

Critical Spec: 1 in Pipe Size

The single specification that decides fit is the pipe inside diameter range of 0.86 in to 1.02 in for a nominal 1 in pipe. Verify the actual pipe ID before ordering because the plug will not seal outside this window. Maximum back-pressure ratings of 40 psi air and 92 ft of water head define the test limits you can safely apply.
