Miller Smith Silverline 120 Series 2-Stage Regulator, CGA 540, 0-50 PSI

Precision Control for Professional Environments

When your work demands unwavering accuracy and reliability, the Miller Smith Silverline Series 121-20-08 Two-Stage Regulator delivers. Designed for professionals in laboratories, maintenance shops, and general plant facilities, this regulator takes the guesswork out of gas control. Unlike standard single-stage regulators that may allow delivery pressure to drift as your gas cylinder empties, this two-stage model compensates automatically, providing a steady, consistent flow from the start of the tank until it is nearly empty.

Built to Last

Durability is at the core of the Silverline series. The regulator features a solid brass body that is machined from bar stock—not forged—ensuring structural integrity. It is then finished with a high-quality plating on the body, bonnet, and gauges, giving it a professional appearance that resists tarnish and corrosion. Inside, Miller's proprietary Sure-Seat technology protects the vital sealing components from microscopic debris, ensuring that your regulator performs like new for years to come.

User-Friendly Design

Reading your pressure settings is effortless thanks to the large, 2-1/2 inch gauges that provide clear, single-scale readings. Whether you are working with Oxygen, Nitrogen, Argon, or other non-corrosive gases compatible with a CGA 540 connection, this regulator offers a delivery range of 0-50 PSIG, perfect for low-to-medium pressure applications. Safety is also prioritized with a preset relief valve that vents to the atmosphere. Upgrade your gas equipment setup with a regulator that combines precision engineering with rugged industrial quality.
