Inline brass ball valve with 1/4-inch MNPT connections rated to 1000 psi CWP

  • Full-port design allows unrestricted flow

Quarter-Turn Brass Ball Valve

This quarter-turn brass ball valve provides on-off flow control for residential and light-commercial plumbing. The 1/4-inch MNPT inline connections suit standard threaded pipework. A full-port design maintains unrestricted flow through the valve body. The lever handle allows quick manual operation.

Thermal And Pressure Limits

The valve body withstands a maximum pressure of 1000 psi CWP across a temperature range of -40 to 300 degrees Fahrenheit. Chrome-plated brass ball and PTFE seats resist corrosion and maintain seal integrity. Blowout-proof stem construction prevents stem ejection under pressure. No electrical power is required for operation.

Included Components And Compliance

The valve ships as a single assembled unit with a steel lever handle installed. PTFE body seals and seats are factory-fitted. California Proposition 65 warnings apply for chemicals known to cause cancer and reproductive harm. No additional accessories, software or installation hardware are bundled.

Questions about this item

How do I install the 1/4" MNPT brass ball valve inline without damaging the threads?

Wrap PTFE tape clockwise on the male NPT threads, hand-tighten, then use a wrench on the hex flats for one to two turns; over-tightening cracks the brass body.

What maintenance will the PTFE seats and stem seals need over time?

Cycle the lever quarter-turn monthly to prevent seizing; if drips appear at the stem or ports, replace the valve — seats and seals are not serviceable.

At what pressure limit does the 1000 psi CWP rating become the limiting factor during sustained use?

The 1000 psi cold working pressure is the first hard limit; do not exceed it at any temperature up to 300 °F.
