621-40060000 - Miller Smith Silverline 620 Series High Purity Two-Stage Regulator, CGA 350, 0-60 PSI

Reliable Two-Stage Performance

The Miller Smith 621-40-06-00-00 Silverline Regulator represents the gold standard in gas regulation for industrial and laboratory professionals. Built on the reliable 620 Series platform, this two-stage regulator is designed to deliver consistent pressure performance in demanding environments. By stepping down cylinder pressure in two stages, it eliminates the "droop" often associated with single-stage regulators, ensuring your equipment receives a steady flow of gas from the start of the cylinder to the bottom.

Heavy-Duty Construction

Durability meets precision in this high-purity brass regulator. The body is machined from brass bar stock and nickel-plated for superior resistance to wear and corrosion. Inside, a stainless steel diaphragm provides the sensitivity needed for accurate pressure adjustments while offering a longer service life than rubber alternatives. The regulator is rated for a maximum inlet pressure of 3500 PSI, making it compatible with high-pressure cylinders commonly used in the industry.

Versatile Installation Features

Designed for versatility, the Silverline 620 features threaded front and rear bonnets, making it easy to panel mount for fixed installations or test benches. The 2-1/2 inch single scale gauge is easy to read, allowing operators to monitor pressure at a glance. Whether you are setting up a laser cutting system, a research station, or a specialized welding application requiring hydrogen or methane mixtures, this regulator provides the control and safety features necessary for a professional setup. It comes equipped with a 1/4" FNPT outlet connection, often paired with a needle valve for fine flow adjustments.
