3/8" FNPT Brass Ball Valve

This 3/8 inch FNPT brass ball valve provides manual two-way flow control for water and combustible gases. It features a two-piece straight body with a full-port chrome-plated brass ball and a locking handle for secure operation. The valve suits residential and light commercial plumbing installations.

Thermals noise and power draw

As a passive mechanical valve it generates no heat, produces no noise and draws no electrical power during normal operation. The brass construction handles operating pressures up to 600 psi and supports vacuum service to 29.92 in Hg. No external energy source is required for actuation.

600 psi pressure rating

The maximum operating pressure of 600 psi determines whether this valve matches the system design. Installations that exceed this rating or require steam service ratings must select a different component. Buyers needing higher pressure limits or certified steam ratings cannot use this valve.

Questions about this item

How do I install this 3/8" FNPT brass ball valve inline without damaging the threads?

Apply PTFE tape or pipe dope to the male threads only, thread the valve onto the pipe by hand until snug, then tighten with a wrench on the valve body hex — never on the handle — to avoid cracking the brass body.

What maintenance or replacement will the chrome-plated brass ball and PTFE seats need over time?

Inspect the ball and seats annually for mineral buildup or scoring; cycle the handle monthly to prevent seizing; replace the valve if leakage appears at the stem packing or ball seal.

At what pressure limit does the 600 psi rating become the governing factor during sustained water or gas service?

The 600 psi maximum operating pressure is the primary limit; sustained pressure above this rating will cause seal deformation and body stress long before the 29.92 in Hg vacuum rating is approached.
