Airgas Model C444D660 Supelcoat™ Coated Stainless Steel High Purity Single Stage Pressure Regulator With 1/4" FNPT Connection And Threadless SeatThese 316 stainless steel single stage high purity regulators are recommended for non corrosive analytical, mildly corrosive and process applications where precise flow control is not critical. A specially designed, convoluted Hastelloy C 22 diaphragm provides good regulating performance and maximum purity integrity without the need for a soft seal, which often can be a source of contamination. Each regulator is capable of withstanding an internal

This two-stage regulator is recommended for use with non-corrosive gases in applications where an ultra-low delivery pressure is required
