Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, CGA 580, 0-100 PSI

Industrial Reliability Meets Laboratory Precision

For professional welders and fabricators who demand the absolute highest quality in gas delivery, the Miller Smith 222-20-09 Silverline Regulator bridges the gap between industrial durability and laboratory precision. While designed for analytical applications, this two-stage regulator is an excellent choice for critical TIG welding applications, such as titanium or aerospace alloys, where shielding gas purity and flow stability are non-negotiable. The two-stage mechanism provides a constant delivery pressure throughout the life of the cylinder, meaning you won't experience flow surge or starvation as your tank runs low, preventing weld defects and rework.

Built for Performance

The Miller Smith 222-20-09 is outfitted with a CGA 580 connection, making it compatible with standard inert gas cylinders like Argon, Helium, and Nitrogen. Its stainless steel diaphragm offers a distinct advantage over standard rubber diaphragms by providing a non-permeable barrier that maintains the strict purity of your shielding gas. This is particularly important in high-spec welding where even trace amounts of atmospheric contamination can compromise the weld integrity. The regulator also features a built-in capturable preset safety relief valve, adding an essential layer of safety to your setup.

Rugged Design for Tough Environments

Miller Smith is synonymous with quality, and the Silverline series is no exception. The regulator features a plated brass body and bonnet constructed from solid bar stock, ensuring it can withstand the rigors of daily use. The large 2-1/2 inch gauges are easy to read from a distance, allowing for quick checks of cylinder and delivery pressure. With a delivery range of 0-100 PSI and a 1/4" MNPT needle valve outlet, this regulator gives you fine-tuned control over your gas output. Whether you are calibrating equipment or performing high-stakes welding, the 222-20-09 delivers the consistent performance professionals trust.
