    Air-Inflatable Plugs

    Style B

    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.

    Style B

    Ribbed Body—Plugs with a ribbed texture have better traction against pipe walls than plugs with a smooth texture. When sealing oily or polished walls, they’ll resist slipping.
    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.

    Air- and Water-Inflatable Plugs for Wye-Joints

    Image of ProductInUse. Front orientation. Contains Inset. Expansion Plugs. Air- and Water-Inflatable Plugs for Wye-Joints.
    These extra-long plugs allow you to seal off two pipes at the same time. They have two separate inflation chambers to release back pressure gradually and prevent splash back as water clears the drain line. To inflate with air, use a hand pump (sold separately). Whether you fill with air or water, a pressure relief valve will prevent over expanding.
