Need a reliable, chemically resistant valve for lab or industrial fluid handling? This 2-way PTFE stopcock valve is built for demanding applications. It's constructed from virgin PTFE (for the body and compression ferrules) and PVDF (for the nuts and ferrule-gripper), making it highly resistant to a wide range of aggressive chemicals and solvents. The valve features one 1/8-inch female NPT port and one 1/4-inch male NPT port, with a 0.11-inch orifice. The stopcock design allows for positive on/off control of flow. It's compatible with other NPT fittings and is made in the USA. Perfect for chromatography, semiconductor processing, chemical feed lines, or any system where purity and corrosion resistance are critical. Ensure leak-free, contaminant-free fluid control.
