T-Handle Expansion Plugs
Twist the easy-grip T-handle 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.
Plugs with a zinc-plated steel plate have fair corrosion resistance.
Plugs with a stainless steel plate have excellent corrosion resistance.

Quick-Lock Expansion Plugs
Save time sealing off pipe or valve box openings. These plugs install with one quarter turn of the handle, unlike wing nut expansion plugs that require multiple turns. They temporarily close off your line with plastic feet that expand mechanically. The feet create a longer-lasting seal than plugs that expand with internal pressure, which can loosen over time. Since these plugs have no pressure ratings, they’re best for low-pressure applications. They’re often used in valve boxes to keep out dirt and debris.
Plugs with a blue handle often signify a closed-off water line.
Plugs with a black handle often signify a closed-off wastewater line.
Expansion Plugs with Bypass
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. 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.
Styles E and F have a barbed bypass for quick connections to tubing.
For Styles F and G, twist the easy-grip T-handle to expand the seal.
Styles G, J, and K have a Schrader valve bypass. An internal spring holds the valve shut until you depress the pin, giving you control over air flow.
