The MESA 200 Series specialty gas regulators are precision manufactured from machined bar stock. This design minimizes contamination of the gas stream by in-board diffusion of atmospheric contaminates. The design of this high-purity gas regulator also minimizes cross-contamination of the gas stream as is frequently encountered with less expensive forged body regulators.


This specialty high purity gas regulator is recommended for delivering constant pressure gas, even in corrosive conditions.  Additional custom configurations are available, please contact us for any special requests. 


All high purity gas regulators are sold complete with inlet CGA, two gauges and a diaphragm packless outlet control valve.


Recommended Applications Series 200 Regulator


The two stage specialty gas cylinder regulator is recommended where delivery pressure must be maintained constant as the cylinder pressure decreases. These specialty gas regulators are ideally suited for continuous withdrawal of gas from pressurized cylinders.

Brass bodies are recommended for non-corrosive gases. Chrome plated brass bodies are also recommended for non-corrosive gases. The addition of chrome plating to the brass body helps to protect the outside body of the specialty gas regulator from corrosive ambient conditions such as found in chemical plants and refineries. 316L Stainless Steel bodies are recommended for mildly corrosive gases. Monel and Hastelloy bodies are available upon special request.
