Cole-Parmer® Single-Stage Gas Regulators

Ideal for corrosive or noncorrosive gas applications. Designed and constructed for diffusion resistance and easy cleanup. Only brass, stainless steel (SS), PTFE, and Kel-F� contact the operating media.
Metal diaphragm, packless valves, and high-purity seals minimize or eliminate outgoing and inboard diffusion. Supplied with SS screen filter (25 µm); and brass body, bonnet, and gauges. Single-Stage High-Purity Regulators are recommended for analytical work where precise pressure control is not critical.
