Miller Smith Silverline 620 Series High Purity 2-Stage Regulator CGA 350

Reliable Gas Delivery for Specialty Projects

When your work demands more than just a standard industrial regulator, the Miller Smith 622-00-06-00-00 Silverline Series steps up to deliver high-purity performance. This two-stage regulator is built for professionals who need absolute consistency in their gas flow. Unlike standard single-stage models that can drift as your tank gets low, this two-stage powerhouse maintains a rock-solid 0-100 PSI delivery pressure from a full tank down to empty. This means you can focus on your process rather than constantly tweaking your regulator settings.

Constructed with a nickel-plated brass body, this regulator is as tough as it is precise. It is specifically outfitted with a CGA 350 connection, making it the correct choice for fuel gases like hydrogen and methane. The internal components are designed for longevity and safety; the stainless steel diaphragm offers superior sensitivity and durability compared to rubber diaphragms, and the metal-to-metal seals ensure no leaks develop over time. A filtered seat adds an extra layer of protection, catching any particles from the tank before they can damage the regulator's internal mechanism.

Safety is a top priority when dealing with flammable specialty gases. That is why Miller Smith equipped this model with capturable vents. In the unlikely event of a diaphragm failure, gas is contained and can be vented safely away from the work area through the 1/16" FNPT ports. Whether you are setting up a laser system, a research rig, or a specialized welding application requiring high-purity fuel gas, this Silverline regulator provides the control, safety, and reliability synonymous with the Miller and Smith Equipment names.
