Mechanical pipe plug for 5 in lines

The Cherne 269956 is a mechanical pipe plug designed to seal 5 in diameter lines during testing or maintenance. Its natural rubber sealing element expands against the pipe wall to create a temporary blockage. The unit is built with a galvanised steel plate for structural rigidity. It is intended for professional plumbing and pipeline work.

Suited for 4.8 to 5.19 in inside diameters

This plug fits pipes with an inside diameter between 4.8 in and 5.19 in, making it suitable for standard 5 in pipe sizes. It is not for lines outside this range or for applications requiring a permanent installation. Buyers needing a bypass connection or a water fill port should look at a different model.

Rated for 18 ft of water head back pressure

The single specification that decides suitability is the maximum back pressure rating of 18 ft of head for water and 8 psi for air. This limit determines whether the plug can safely hold the test pressure required on a specific job. Exceeding this rating risks seal failure and potential injury.

Questions about this item

Is the 5 in Cherne 269956 the right size for a 5 in pipe with an inside diameter near 5 in?

The 269956 fits pipes with an inside diameter from 4.8 in to 5.19 in, so it covers standard 5 in pipe sizes.

What does the 18 ft of head water back-pressure rating mean when the plug is installed?

It holds a water column equivalent to 18 ft of head before leakage can occur.

Does the mechanical plug use a specific pipe-thread standard for sealing?

No pipe-thread standard applies; the natural-rubber body expands against the pipe wall to seal.
