Dual-Stage Ultra-High-Purity Chrome-Plated Brass Regulators
• Oxidation-resistant, chrome-plated.
• Most stable outlet pressure control throughout the life of a high-pressure gas cylinder.
• Secondary pressure regulation not needed.
• Most widely used regulator.
• Less internal volume than stainless steel regulators.
