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. Inflate with a hand pump (sold separately); an air compressor may overinflate the plug and cause damage. Tether the plugs using either the eyebolt or chain/ring so they don't get lost or stuck in your pipes. 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.

Air- and Water-Inflatable Plugs

Penetrate tight pipe junctures with the most flexible expansion plugs we offer. 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. 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.

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. 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.
