Airgas Model N245G580 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

high-purity 316 stainless steel regulators is designed for non-corrosive analytical and process applications requiring precise

with its 316 stainless steeldiaphragms

These regulators also have a check valve cylinder connection that prevents contaminates from entering during cylinder changeover

Preset Safety Relief Valve - prevents excessive pressure buildup

Red OSHA perimeter marker flags measure 105' in length and have 7 1/2" x 17" red pennants

allows the exterior surfaces to maintaina good appearance in outdoor environments

A diaphragm packless outlet valve with a 1/4" compression tube fitting is provided for flow control and to maintain system purity

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

extend service life

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

provides precise pressure control from full cylinder to almost empty

The regulator has a unique design to reduce weight and make the regulator more durabe
