1/4" FNPT x MNPT Brass Ball Valve

This 1/4-inch FNPT x MNPT brass ball valve provides inline flow control for residential and light-commercial plumbing. Its two-piece brass body and full-port design allow unrestricted passage when open. The lever handle offers quick quarter-turn operation for easy shut-off or isolation. Suitable for installers needing a compact, corrosion-resistant valve for water, air or compatible fluids.

1000 psi CWP Pressure Rating

The valve is rated to 1000 psi cold working pressure, making it suitable for high-pressure supply lines and compressed-air systems. PTFE seats deliver reliable sealing across the stated temperature range of -40 °F to 300 °F. A blowout-proof brass stem prevents stem ejection under pressure, enhancing safety during service. This rating is the primary factor in deciding whether the valve meets the system design requirements.

Inline Installation with Lever Handle

The FNPT x MNPT connections allow direct threading into female and male pipe fittings without additional adapters. Brass construction resists dezincification in potable-water applications, while the steel lever handle provides mechanical advantage for operation. The compact inline body frees up space in tight mechanical rooms or cabinetry. Installers should verify thread compatibility and chemical compatibility with the intended media before assembly.

Questions about this item

What does the 1000 psi CWP rating mean when the valve is installed in a plumbing system?

The 1000 psi CWP rating indicates the maximum cold working pressure the brass body and PTFE seats can handle continuously in a water, oil or gas line at ambient temperature.

How does the FNPT x MNPT connection affect what pipe or fitting can be attached?

One end has female National Pipe Thread and the other has male National Pipe Thread, so the valve threads directly into a 1/4 inch female fitting on one side and accepts a 1/4 inch female fitting on the other.

What clearance is needed for the steel lever handle to operate?

The lever handle extends from the top of the stem and must be able to swing through a quarter turn without striking adjacent pipe, insulation or cabinet walls.
