Airgas Model C444F660 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

The optional bonnet vent adapter enables venting hazardous gases in the event of diaphragm failure

These regulators come with a CGA-nipple that has a special high-purity

Self-closing lid is operated with the included foot lever and opens no more than 60 degrees

along with the composite bonnets

single-stage regulators are engineered to provide precision performance

allowing minimal internal volume and eliminating large cavities and pockets associated with forged-body regulators

This minimizes cleanup time in vacuum purging and yields lower residual contaminant levels

These regulators have a unique design to reduce weight and make the regulatormore durable

06 psig for every 100 psig of inlet pressure decay

Machined from brass bar stock

This series of nickel-plated brass two-stage high purity regulators is designed for non-corrosive analytical
