1/4" FNPT x MNPT Stainless Steel Ball Valve
This quarter-turn ball valve uses 316 stainless steel for the body ball and stem with PTFE seats and seals. It connects a 1/4 inch female NPT thread to a 1/4 inch male NPT thread in an inline two-piece body. The full-port design matches the 1/4 inch hose inside diameter for unrestricted flow.
Installation and common issues
Thread the male end into the female port using pipe sealant or tape rated for stainless steel. The butterfly handle requires minimal clearance to operate through ninety degrees. The blowout-proof stem prevents the stem from ejecting under pressure. Over-tightening can damage threads or distort the PTFE seats causing leaks.
Compatibility checks
Verify that the system pressure does not exceed 1000 psi cold working pressure or 150 psi steam working pressure. Confirm the media temperature stays within minus 40 to 400 degrees Fahrenheit. Ensure the mating pipe threads are 1/4 inch NPT and that the fluid is compatible with 316 stainless steel and PTFE materials.

Questions about this item
How do I confirm the valve is sealing correctly after installation?
Pressurise the line up to the 1000 psi CWP rating and check for leaks at the FNPT and MNPT threads; the blowout-proof stem and PTFE seats should hold pressure without weeping.
What comes with the valve and what must I supply?
The valve ships as a single 316 stainless steel inline unit with butterfly handle; you must provide 1/4 in pipe tape or sealant and matching FNPT/MNPT fittings for your piping.
Which pressure and temperature rating should I select for my application?
Choose this model when your system runs up to 1000 psi CWP, 150 psi WSP steam, and between -40 and 400 degrees F; the full-port 1/4 in bore matches those limits.
