Square-Head Expansion Plugs
Turn the square head of the plug into the sealing ring to 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.
