1/8" FNPT x MNPT Brass Ball Valve

This quarter-turn brass ball valve connects a female NPT thread to a male NPT thread in a 1/8 inch pipe size. It is suited for installers who need an inline shut-off in air, water or oil lines up to 1000 psi CWP. The full-port design maintains flow without restriction through the valve body.

Upgrade from gate or globe valves

Gate and globe valves often leak at the stem packing after repeated cycling. This ball valve uses a blowout-proof stem and PTFE seats that seal reliably over a temperature range from -40 to 300 degrees F. The jump is worth it when a compact lever handle and zero-leakage shut-off are required for frequent operation.

Limits of NPT threads and PTFE seats

Tapered NPT threads rely on thread engagement and sealant; over-tightening can crack the brass body or strip the threads. PTFE seats soften above 300 degrees F, so the valve must not be used in steam or high-temperature service beyond that limit. California Proposition 65 warnings apply due to chemical content.

Questions about this item

What pipe size and thread type does the 1/8" FNPT x MNPT brass ball valve use for mounting?

The valve has a 1/8 inch pipe size with FNPT x MNPT connection type for inline installation.

How is the lever handle installed on the blowout-proof stem, and what step is often missed?

The lever handle mounts on the brass blowout-proof stem; ensure the handle is fully seated and aligned with the ball port for correct open/close indication.

When should the PTFE seats be inspected or replaced given the pressure and temperature ratings?

Inspect PTFE seats periodically when operating near the 1000 psi CWP rating or across the -40 to 300 degrees F temperature range to maintain sealing performance.
