Miller Smith Silverline 620 Series Two-Stage High Purity Regulator, CGA 580, 0-250 PSI

Reliable Purity for Critical Welding and Lab Work

When your work involves sensitive materials or precise analytical equipment, standard industrial regulators often fall short. The Miller Smith Silverline Two-Stage Regulator (623-03-09-00-00) bridges the gap between industrial durability and laboratory precision. Designed for use with inert gases like Argon, Nitrogen, and Helium (CGA 580), this regulator is an excellent choice for high-end TIG welding setups where shielding gas consistency is non-negotiable, as well as for purging and blanketing applications.

The "Two-Stage" feature is the standout benefit for professional users. It automatically compensates for the drop in cylinder pressure as you work, meaning you won't have to constantly adjust your settings to maintain the correct flow or pressure. The regulator features a large 2-1/2 inch single scale gauge that is easy to read, and the bonnet includes a capturable vent for safety. With its nickel-plated brass body, it resists corrosion and wear better than standard brass regulators, while the stainless steel diaphragm ensures that no impurities are introduced into your gas line.

Whether you are setting up a laser system, a gas chromatograph, or a critical welding station, the Miller Smith Silverline delivers the consistent performance you need. The 1/4 inch tube fitting outlet allows for easy connection to standard high-purity tubing, and the robust construction ensures a long service life even in demanding environments. Trust Miller Smith to deliver the control you need for your most critical projects.
