Airgas Model C441B Stainless Steel High Purity Single Stage Line Regulator With 1/4′′ FNPT Connection And Threadless Seat

This series of 316 stainless steel high-purity, single-stage line regulators is recommended for applications where diffusion resistance is required. These regulators are recommended for use on low-pressure pipelines serving gas chromatographs, mass spectrometers, research sampling systems, and semiconductor processing. The specially-designed, convoluted Hastelloy? C-22 diaphragm provides accurate, stable delivery pressure and is capable of withstanding internal vacuum purging. These units are easily mounted to panels using the optional panel-mount nuts with the threaded bonnet. Two 10 x 32 UNF-threaded holes in the body allow for bracket or external panel mounting. The optional bonnet vent adapter allows venting of hazardous gases in the event of diaphragm failure.
