Parker C552104 Plug Valve 250 Psi 1/4 Inch Mnpt Nitrile

Product Description

The PARKER C552104 is a 1/4 inch instrumentation plug valve designed for precise flow shutoff in instrumentation and process piping systems. It features a brass body with a nitrile seal and a lever handle for quick quarter-turn operation. Rated to 250 psi maximum working pressure, this valve handles temperatures from -40 degrees F to 175 degrees F, making it suitable for a wide range of industrial and commercial instrumentation applications. It ships in a package quantity of two and is intended for installation by licensed plumbers, pipefitters, or instrumentation technicians.

This valve is used in instrumentation tubing and small-bore process lines where a compact, reliable shutoff is required. The MNPT x MNPT end connection on both sides allows direct threaded installation into standard NPT fittings. Typical applications include gauge isolation, sample lines, and instrument impulse lines in commercial and light industrial settings. The nitrile seal material is compatible with a broad range of media including air, water, and many petroleum-based fluids. Package includes 2 valves per unit.
