The CONCOA 213 Series is a chrome-plated forged brass, dual-stage regulator designed for primary pressure control of low-pressure, non-corrosive, liquefied, or high-purity inert gases (up to grade 4.5). Its two-stage design ensures stable delivery pressure, compensating for cylinder depletion, with adjustable outputs as low as 0.1 PSIG (7 mBAR) in 0.05 PSIG (4 mBAR) increments, making it ideal for atmospheric or sub-5 PSIG (350 mBAR) applications.

Features:

• Fine-adjusting screw for precise pressure control

• 316L stainless steel diaphragm prevents inboard diffusion

• CAPSULE® seat design with 360° filtration in both stages

• Standard relief valve protects diaphragm and gauges

• Helium leak-tested for integrity
