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 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.
