Wing-Nut Expansion Plugs

Style A

Style B

Style C

Style F

Twist the wing nut on these plugs to expand the seal and close off pipe openings.

Style A—Style A aren’t recommended for pressure testing, so they’re often used as a dust cover.

Style B—Style B have a wide top flange so they don’t fall into your pipe. They’re often used for plumbing pressure tests.

Style C—Style C are the easiest to grip. The handle has more surface area than that of our other styles.

Style F—Style F have flanges of the same size, so you can install them as deep as needed. Rated for higher pressures than our other styles, they’re ideal for leak testing.

Plastic Plate—Plugs with a plastic plate weigh less than plugs with a metal plate.

Zinc-Plated Steel Plate—Plugs with a zinc-plated steel plate have fair corrosion resistance.

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-Inflatable Plugs


Style A	Style B	Style C

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.

With Zinc-Plated Steel Chain/Ring


Style A	Style B	Style C

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

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.

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—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.

Expansion Plugs for Cleanout Tees

Seal cleanout tees when testing your drain, waste, and vent systems for pressure and leaks—no need to inflate these plugs with an air compressor or hand pump. To install, insert the plug end into your pipe so the curved foot is on the bottom threads of the cleanout tee, then push down the handle to lock it into the foot. The foot has a two-stage release latch: lift the handle one notch to release the plug and allow liquid to drain slowly, then lift the handle again until the foot fully disengages to take out the plug.

Remote-Access Air-Inflatable Plugs

Plug underground sewage lines, water supply lines, and other pipe that’s hard to reach. These plugs attach to a 6-ft. extension pole with an adapter (both sold separately) so you can place them in confined spaces from a distance. Before placing them in your line, connect them to your air compressor with a hose to inflate them remotely. Also known as pneumatic plugs, they’ll seal wide and out-of-round pipe. Since they can lose pressure over time, they’re intended for temporary seals. Use them in lower-pressure applications than water-inflatable plugs.

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

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—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.
