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.

Air-Inflatable Plugs for Tee Connections
Often used for plumbing tests, these plugs thread into tees and inflate to block flow across the pipe. After your test is complete, deflate the bladder to drain the fluid from your line. Leave the plug installed while the draining the pipe—the threads create a leak-free seal, so no water will splash out. Also known as pneumatic plugs, they can lose pressure over time, so they’re designed for temporary seals. To inflate, use a hand pump (not included) since an air compressor might overinflate and burst them.
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-Inflatable Plugs with Bypass
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. Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve pressure while testing.
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 during installation. Pull on the tether for quick and easy removal once testing is complete.
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.
