Foreman Isolation Pipe Plug

Lightweight, Rugged, Easy-to-Install - Available to rent or purchase.


The Foreman Isolation Plug is composed of two aluminum discs that are pressed together through the tightening of the central bolt. As the discs press together, the surrounding rubber gasket will expand, ensuring a tight fit around the inside diameter of the pipe. The plug also comes with a removable vent cap which can be used to release accumulated substances inside the pipe.


Because Foreman Isolation Plugs are made from rugged, lightweight cast aluminum, most sizes can easily be installed by one person. This plug is not rated to hold back-pressure and should only be used for isolation; however, for situations involving back-pressure, we recommend using the GripSafe®ST family of high pressure isolation and test plugs..
