Airgas Model N245G590 Brass High Purity Single Stage Pressure Regulator With 1/4” FNPT Connection And Non-Lubricated Check ValveThese brass, single stage, high purity regulators are recommended for non corrosive analytical and process applications where precise flow control is not critical. A specially designed, convoluted, stainless steel diaphragm with metal to metal seals provides good regulating performance and maximum purity integrity without the need for a soft seal, which often can be a source of contamination. These regulators come with a CGA nipple that has a special

non-corrosive gas

This series is ideally suited for chromatographiccarrier gas applications including FID

Hastelloy® C-22 diaphragms that provide maximum sensitivity

These regulators are recommended for non-corrosive analytical and process applications

The valve is built into the regulator body reducing the gas path

ultra-low delivery pressure gases

The two-stage design yields a delivery pressure change ofless than 0

extending regulator service life while also reducing velocity of gas when opening high-pressure cylinder valves

The two-stage design yields a delivery pressure change of less than 0

These nickel-plated single-stage ultra high purity regulators are recommended for non-corrosive analytical
