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.

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. 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 E and F have a barbed bypass for quick connections to tubing.
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.
