These Regulators are recommended for the delivery of noncorrosive high purity gases and calibration mixtures used in gas chromatography and other sensitive laboratory equipment. They offer maximum control of delivery pressure regardless of fluctuations in cylinder pressure. Both diaphragms are stainless steel, which will not contaminate the gas stream and are highly resistant to inboard diffusion of atmospheric contaminants.


  • Pure- Stainless steel diaphragms offer resistance to inboard diffusion of contaminants.
  • Dependable- Kel-F seats and double inlet filtering offer longer life with less maintenance.
  • Safe- External self-reseating relief valve provides maximum regulator protection.
  • Durable- All components are chrome-plated giving long lasting durability and attractive appearance.
