Wing-Nut Expansion Plugs
 |  |
Style A | 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 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.
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.
