Airgas Model 311A580 Brass-Plated Bar Stock Noncorrosive Gas Two Stage Regulator With CGA-580 Connection

These economical plated-brass cylinder regulators are specially suited for use in applications and environments requiring both high reliability and diffusion resistance. Sensitive, extra long-life stainless steel diaphragms ensure high purity and leak integrity of specialty gases. The cartridge valve design with integral filter protects the regulator seat from particulate contamination and makes servicing simple and cost-effective. Two-stage design provides constant delivery pressure with no need for periodic readjustment as cylinder inlet pressure declines.
