Wing Nut Expansion Plugs
Twist the wing nut on these plugs to expand the seal and close off pipe openings. 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.
A wide top flange on Style B stops these plugs from falling into pipes.
Style E have an eyebolt that allows you to tether or hang these plugs for convenient storage.

Deep-Reach Wing Nut Expansion Plugs
Plate With
Brass Stem
Insert these plugs deep within your pipe to temporarily block off a line. Twist their wing nut to expand the seal. 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.
Plugs with a stainless steel plate have excellent corrosion resistance.

Deep-Reach Hex Nut Expansion Plugs with Bypass
Plug your pipe from the inside. Insert these expansion plugs deep into your pipe, and then tighten the nut on the stem. Use the bypass tube to add air, water, and fluid or relieve back pressure. 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.
