Metal Round Caps

More durable than plastic caps, these provide the most protection from abrasion and impact.

Steel caps are stronger than aluminum.

Aluminum caps have good corrosion resistance, are lightweight, and are nonmagnetic.

Stainless steel caps have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.

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.
