Wing-Nut Expansion Plugs


Style A	Style C

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

Style E—Style E have an eyebolt, so you can tether or hang them for convenient storage.

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.

Stainless Steel Plate—Plugs with a stainless steel plate have excellent 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.
