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.
