Airgas Model N245A590 Brass High Purity Single Stage Pressure Regulator With 1/4” FNPT Connection And Non-Lubricated Check Valve Regulator The metal-to-metal diaphragm seal prevents

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 10–8ccs helium

Captured bonnet ports with optional vent adapters are standard on both stages and allow the venting of hazardous gases in the event of diaphragm failure

Convoluted Hastelloy C-22 diaphragms provide excellent regulating characteristics and allow for internal vacuum purging

Airgas Model N245A590 Brass High Purity Single Stage Pressure Regulator With 1/4” FNPT Connection And Non-Lubricated Check Valve Regulator The metal-to-metal diaphragm seal preventsThese 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
