Value Brand 1WML2 1/8" FNPT Brass Ball Valve Inline

SKU CH-454F-7GEEE

Inline brass ball valve with full-port flow, PTFE seats and a blowout-proof stem rated to 1000 psi from -40 to 300 degrees F

  • Inline full-port design maintains unrestricted flow
  • Brass body with PTFE seats resists corrosion up to 300 °F
  • Blowout-proof stem prevents accidental ejection under pressure
  • Steel lever handle gives positive on/off control
  • Rated 1000 psi CWP for demanding water and air lines

Brass inline ball valve 1/8 FNPT

This 1/8 inch FNPT brass ball valve provides inline flow control for water, air and compatible fluids. The full-port design maintains unrestricted passage when open. A blowout-proof stem and PTFE seats support reliable sealing across the rated pressure and temperature range.

Upgrade from basic shut-off valves

The 1000 psi CWP rating and -40 to 300 degrees F range suit applications where standard plumbing valves fall short. Full-port construction eliminates the flow restriction common in reduced-port alternatives. PTFE seats resist chemical attack better than elastomer seals in many industrial fluids.

Limits of FNPT threaded connections

Threaded FNPT joints require proper sealant and torque to prevent leaks at the 1000 psi rating. Brass body and stem limit use with highly corrosive media that attack copper alloys. The lever handle needs clearance for quarter-turn operation in tight pipe runs.

Questions about this item

What size threads does the 1/8" FNPT brass ball valve need for installation?

The valve uses 1/8 inch female NPT threads on both ends, so matching male NPT fittings are required for a proper seal.

How should PTFE tape be applied on the FNPT connections to avoid leaks?

Wrap PTFE tape clockwise on the male threads only, covering the threads completely without overhanging the pipe end, then tighten to the recommended torque.

When should the PTFE seats be inspected or replaced in this brass ball valve?

Inspect the PTFE seats if the valve shows seepage or becomes hard to operate; replacement is needed when the seats no longer seal at the rated 1000 psi CWP.
