Airgas Model C441F Stainless Steel High Purity Single Stage Line Regulator With 1/4" FNPT Connection And Threadless Seat

Product Description

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.

Features

Bonnet Vent Ports (with optional bonnet vent adapters) allow venting of hazardous gases in the event of diaphragm failure. Standard Threaded Bonnet (with optional collar-mount nuts) for easy panel mounting. High-Flow Capacity permits excellent pressure control for multi-instrument applications. Threadless Seat Design provides longer regulator life.
