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.
