Air-Inflatable Plug

Manufacturer part: 3058K25

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.
