1/2" FNPT Nickel Brass Ball Valve
The Legris 0492 10 21 valve is a manual two-way ball valve built for inline installation. Its nickel-plated brass body and ball suit air, gas and water lines in residential or light commercial plumbing. The full-port design maintains flow without restriction.
Thermals noise and power
This mechanical valve has no electrical components, so it generates no heat, noise or power draw during operation. Pressure ratings reach 174 psi for general use and 175 psi for steam service. No vacuum or combustible gas ratings are provided.
Build quality and connections
The one-piece brass construction reduces potential leak paths compared to multi-piece designs. The 1/2" FNPT threads connect directly to standard female pipe fittings without adapters. A non-locking handle allows quick manual actuation but does not prevent accidental movement. Not rated to 3-A sanitary standards.

Questions about this item
How do I install the 1/2" FNPT nickel brass ball valve inline and what step is often missed?
Wrap the female NPT threads with PTFE tape or pipe sealant, thread the valve on by hand then tighten with a wrench on the body flats, and remember to orient the handle so it can rotate freely after the final turn.
What maintenance or replacement will the Legris 0492 10 21 valve need over time?
Inspect the nickel-plated brass ball and seats periodically for wear or mineral buildup; if leakage appears at the stem or ports, replace the entire one-piece valve because internal parts are not serviceable.
What is the first pressure limit reached under sustained use with water or air?
The valve is rated for a maximum operating pressure of 174 psi, so continuous service above that pressure will exceed the design limit first.
