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 A aren’t recommended for pressure testing, so they’re often used as a dust cover. Plugs with a stainless steel plate have excellent corrosion resistance.

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. The seal expands to temporarily 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.
For Styles A-E and H-L, twist the wing nut to expand the seal.
Styles C and D have an NPT threaded bypass for making leak-tight connections.
For Styles F and G, twist the easy-grip T-handle to expand the seal.
Styles G, J, and K have a Schrader valve bypass. An internal spring holds the valve shut until you depress the pin, giving you control over air flow.

Air-Inflatable Plugs
Conform to wide and out-of-round pipes with these inflatable plugs. Also known as pneumatic plugs, they're designed for temporary seals since they can lose pressure over time. Inflate with a hand pump (sold separately); an air compressor may overinflate the plug and cause damage. Tether the plugs using either the eyebolt or chain/ring so they don't get lost or stuck in your pipes. 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.
