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. Style C are the easiest to grip. The handle has more surface area than that of our other styles. Style E have an eyebolt, so you can tether or hang them for convenient storage. Style F have flanges of the same size, so you can install them as deep as needed. Rated for higher pressures than our other styles, they’re ideal for leak testing.
Plugs with a zinc-plated steel plate have fair corrosion resistance. Plugs with a stainless steel plate have excellent corrosion resistance. Plugs with a plastic plate weigh less than plugs with a metal plate.

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.
Styles E and F have a barbed bypass for quick connections to tubing.
Style H have a bypass with BSPP threads, also known as G threads, for making leak-tight connections.
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.
