Wing Nut Expansion Plugs

Twist the wing nut on these plugs to expand the seal and close off pipe openings. Maximum air back pressure is the amount of pressure a plug can withstand without moving. Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.

Style E have an eyebolt that allows you to tether or hang these plugs for convenient storage.

The flanges on Style F are the same size, which means you can install these plugs inside of pipes as deep as needed.
