Airgas Model N245F 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
