Airgas Model C444D350 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

000 psig inlet pressure

The metal-to-metal diaphragm seal prevents contamination by eliminating the need for a soft seal and provides a leak-rate design of less than 2 x 10-8 ccs helium

These 316 stainless steel single-stage high-purity regulators are recommended for non-corrosive analytical

They are available with a CGA-cylinder valve connection for use on large cylinders

Also for chromatography processes where the gas cannot be compromised by any interaction

which often can be a source of contamination

These have a unique internal design to ensure all surfaces are continually swept

convoluted Hastelloy® C-22 diaphragm provides accurate

This creates consistencies in processes and extends column life in GC applications

This series of 316 stainless steel high-purity

lightweight design is extremely convenient
