Test Plugs

Stemar Test plugs are made of natural rubber with specialized end plates for testing and pressure monitoring applications.

Versatile; can be adapted to work with a leak location kit, set up for blocking only, or customized for a double blocking plug setup with isolated inflation systems.

Common applications include, but are not limited to, pipeline acceptance tests, water tests, sewer air tests, water block & release, and leak location.

Stemar maintains a large inventory of both rental and new plugs up to 96" in diameter.

  • What is the smallest opening this plug has to fit through?

  • Are there any chemicals involved?
