Four-port, stainless steel barstock, point-of-use regulator for ultra-high purity gas applications
The CONCOA 425 Series regulator provides secondary pressure control for ultra-high purity gases, including corrosive and toxic gases, or point-of-use pressure monitoring and control in high purity gas distribution systems. Unlike most pipeline equipment, CONCOA line regulators are rated to full cylinder pressure to ensure safe use in the event of primary pressure control failure.
