620-03030000 - Miller Smith 620 Series High Purity Two-Stage Regulator, CGA 326, 0-25 PSI

Reliable Gas Delivery for Specialty Jobs

When your work requires more than just standard industrial gas control, the Miller Smith Silverline 620 Series steps up to the plate. This high-purity two-stage regulator is built for professionals who need absolute consistency. Whether you are managing specialty gases for a custom fabrication project or maintaining lab equipment, the 620 Series ensures that your gas flow remains steady from the moment you crack the cylinder until it's empty. The two-stage mechanism automatically compensates for dropping cylinder pressure, so you don't have to waste time constantly tweaking the knob to maintain your 25 PSI set point.

Built Tough, Built Clean

The Silverline series combines Miller's legendary durability with high-precision engineering. The body is machined from solid brass and nickel-plated for a clean, professional finish that resists tarnish and wear. Inside, a stainless steel diaphragm replaces the rubber diaphragms found in cheaper units, offering superior lifespan and resistance to temperature changes. This metal-to-metal construction also means there are no rubber seals to dry out or contaminate your gas stream, ensuring that what comes out of the nozzle is exactly what was in the tank.

User-Friendly Features

Designed with the operator in mind, this regulator features large, easy-to-read 2-1/2 inch gauges that let you monitor tank and line pressure at a glance. The CGA 326 fitting is specifically designed for Nitrous Oxide service, ensuring a safe and correct connection every time. For those setting up permanent stations, the regulator includes threaded bonnets that make panel mounting simple and secure. With the added safety of captured vents, you can work with confidence knowing that Miller Smith has engineered this tool to meet the highest safety standards in the industry.
