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.

A wide top flange on Style B stops these plugs from falling into pipes.

Lock Style D with a padlock (not included) to limit access.

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.

Square-Head Expansion Plugs

Turn the square head of the plug into the sealing ring to 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.

Quick-Snap Expansion Plugs

Turn the cam handle to expand the seal, then snap the handle down to hold it in place 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.

Expansion Plugs with Bypass

Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve pressure while testing. 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 G and Style J plugs have a Schrader valve, which has an internal spring that holds the valve shut until you depress the pin, providing control over air flow.
