OVERVIEW

Reliable Gas Delivery for Shop and Lab

For welders, fabricators, and lab technicians who require "set it and forget it" reliability, the Miller Smith 123-82-09 Silverline Regulator is the tool of choice. Standard single-stage regulators often require constant attention; as your gas tank empties, the delivery pressure can fluctuate, leading to inconsistent flow rates that can ruin a weld or invalidate a test. This two-stage regulator solves that problem by automatically compensating for tank pressure changes, delivering a steady stream of Argon, Nitrogen, or other inert gases from start to finish.

Durability is key in any industrial setting, and the Silverline series delivers with its nickel-plated brass construction. Unlike bare brass which can tarnish and degrade over time, the nickel finish protects the regulator from the harsh realities of shop environments, including humidity and minor chemical exposure. The large, easy-to-read gauges allow you to monitor your gas supply and output pressure at a glance, reducing downtime and errors. Whether you are purging piping systems, running pneumatic testing equipment, or supplying shielding gas for critical TIG welding applications, the 0-250 PSI delivery range offers the versatility needed for a wide array of tasks.

Safety and longevity are built-in. The regulator features a preset safety relief valve that vents to the atmosphere, adding a layer of protection when working with non-hazardous gases. The Sure-Seat filtered seat design prevents microscopic particles from damaging the internal sealing surfaces, ensuring that your regulator performs like new for years. Compatible with any standard CGA 580 cylinder, this Miller Smith regulator is a premium upgrade for any professional looking to improve the consistency and quality of their gas delivery system.

FAQ

A two-stage regulator reduces cylinder pressure in two steps, providing a constant delivery pressure even as the cylinder pressure drops. A single-stage regulator may show a slight increase in delivery pressure as the cylinder empties, requiring manual adjustment.

The CGA 580 fitting is the standard connection for inert gases, including Argon, Nitrogen, and Helium. It is also used for certain inert gas mixtures.

While the regulator mechanism is compatible with CO2, the CGA 580 connection is not. Pure CO2 cylinders typically use a CGA 320 fitting. An adapter would be required, or a specific CO2 regulator should be used.

This specific model (123-82-09) has a delivery pressure range of 0-250 PSI.

No, this regulator is designed for inert and non-corrosive gases only. It lacks the stainless steel internals required for corrosive service.

The nickel plating on the brass body and bonnet provides superior corrosion resistance and durability compared to raw brass, keeping the regulator in good condition in shop environments.

Yes, Miller Smith regulators are typically covered by the Miller True Blue Warranty. Please check the specific warranty documentation for the duration, which is often 3 years for regulators.

The regulator is rated for a maximum inlet pressure of 3500 PSI.
