    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 D—Style D lock with a padlock to limit access. They’re often used on monitoring wells.
    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.

    Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve pressure while testing. The seal expands to temporarily close off pipe openings.
    Style A—For Style A, twist the wing nut to expand the seal. They have an NPS threaded bypass for routing moderately pressurized fluids.
    Style B—For Style B, twist the wing nut to expand the seal. They have an NPS threaded bypass for routing moderately pressurized fluids.
    Style C—For Style C, twist the wing nut to expand the seal. They have an NPT threaded bypass for making leak-tight connections.
    Style D—For Style D, twist the wing nut to expand the seal. They have an NPT threaded bypass for making leak-tight connections.
    Style E—For Style E, twist the wing nut to expand the seal. They have a barbed bypass for quick connections to tubing.
    Style H—For Style H, twist the wing nut to expand the seal. They have a bypass with BSPP threads, also known as G threads, for making leak-tight connections.
    Style J—For Style J, twist the wing nut to expand the seal. They have a Schrader valve bypass. An internal spring holds the valve shut until you depress the pin, giving you control over air flow.
    Style K—For Style K, twist the wing nut to expand the seal. They have a Schrader valve bypass. An internal spring holds the valve shut until you depress the pin, giving you control over air flow.
    Style L—For Style L, twist the wing nut to expand the seal. They have a GHT bypass that connects to standard garden hoses. Ideal for pipe cleanout, they allow for easy, controlled drainage.
    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.

    Insert these plugs deep within your pipe to temporarily block off a line. Twist their wing nut to expand the seal.
    Stainless Steel Plate—Plugs with a stainless steel plate have excellent corrosion resistance.
    Plastic Plate—Plugs with a plastic plate are lighter in weight than plugs with a stainless steel plate.
    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.
