213-0309 - Miller Smith Silverline 210 Series High Purity Regulator, CGA 580, 0-150 PSI

High Purity Gas Regulation for Critical Tasks

When your work demands the absolute cleanest gas delivery, the Miller Smith 213-03-09 Silverline Regulator is the tool you can trust. While standard industrial regulators are sufficient for general welding, critical applications—such as aerospace TIG welding, purging, or laboratory-grade testing—require equipment that won't introduce moisture or contaminants into your shielding gas. This regulator is built to meet those high standards, ensuring that the gas leaving the cylinder is exactly the gas that reaches your workpiece or instrument.

The standout feature for professionals is the stainless steel diaphragm. In standard regulators, rubber diaphragms can sometimes release trace chemicals or allow atmospheric moisture to permeate over time. The stainless steel diaphragm in the Silverline series creates a hermetic barrier, guaranteeing that your high-purity Argon, Helium, or Nitrogen stays pure. This is essential when working with reactive metals like titanium or when conducting emissions testing where even parts-per-million contamination can ruin a result. The body and gauges are nickel-plated, offering a durable, easy-to-clean finish that stands up to shop environments while looking professional.

Designed for reliability, the 213-03-09 features a single-stage design that provides steady flow control up to 150 PSI. The large, clear gauges make it simple to monitor your tank levels and output pressure at a glance. It connects easily to standard inert gas cylinders with a CGA 580 fitting. Whether you are setting up a back-purge for a sanitary stainless weld or running a gas chromatograph in a QA lab, this Miller Smith regulator delivers the consistent, contamination-free performance required for high-stakes projects.
