Brass Ball Valve for Water Lines

The Milwaukee Valve UPBA475B is a two-piece brass ball valve designed for water supply piping. Its 1 1/4 inch FNPT connections suit residential and light-commercial plumbing installations. The full-port chrome-plated brass ball maintains flow capacity through the valve body.

Inline Installation with Locking Lever

The straight-body valve threads directly into female NPT pipe ends without extra fittings. A locking lever handle secures the open or closed position against accidental movement. Rated for 600 psi operating pressure, it handles typical municipal and well-system pressures.

Sustained Pressure and Vacuum Service

Under continuous load the valve holds 600 psi water pressure and a vacuum rating of 29.92 in Hg without leakage. Steam and combustible gas duties are not rated, so the valve should be confined to water service. The brass construction resists corrosion during long-term exposure to treated water.
