    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. They’re better for lower-pressure applications than water-inflatable plugs. Inflate them with a hand pump; an air compressor may overinflate the plug and cause damage.
    Plugs with a chain or eyebolt can be tethered through either so they don't get lost or stuck in your pipes during installation. For easy removal once testing is complete, pull on your tether.

    Pressure-Relief Valve—Plugs with a pressure-relief valve release excess pressure to reduce the risk of overinflating and rupturing.
    Maximum Air Back Pressure—Maximum air back pressure is the amount of pressure a plug can withstand without moving.
    Maximum Water Back Pressure—Maximum water back pressure refers to the pressure resulting from the height of the water above the plug.
