Brass ball valve for inline shut-off

This 1/4-inch FNPT brass ball valve provides full-port flow control in residential and light-commercial plumbing. The two-piece body with blowout-proof stem suits installers who need reliable on-off service for water, air or compatible fluids. It is not for applications requiring actuated or automated operation.

Sustained pressure and temperature performance

Rated at 1000 psi CWP, the valve maintains seal integrity under continuous working pressure without the pressure drop common in reduced-port designs. PTFE seats withstand temperatures from -40 to 300 degrees F, so the valve handles hot-water loops and chilled-water lines alike through extended duty cycles.

Thermal stability and manual operation

Brass body and ball resist thermal expansion mismatch across the stated temperature range, preventing stem binding during long hot or cold runs. The steel lever handle transmits torque positively without the flex that can round off softer handles, and the blowout-proof stem eliminates a common leak path under thermal cycling.

Questions about this item

Will the brass body and PTFE seats handle continuous 300 °F service without degrading?

The valve is rated for a temperature range of -40 to 300 °F, and the PTFE seats are chosen for that range. Brass construction resists corrosion in typical water and air lines at those temperatures.

My piping uses 1/4 inch FNPT threads — does this valve connect directly without extra fittings?

Yes, it has FNPT x FNPT ends sized for 1/4 inch pipe, so it threads straight onto matching male NPT nipples or adapters. No additional couplings are required for a standard NPT installation.

Can I keep my existing steel handle lever when I replace the old valve?

This unit comes with its own steel lever handle mounted on a brass stem. The handle is not interchangeable with other brands, so plan to use the supplied lever.
