621-01050000 - Miller Smith Silverline 620 Series 2-Stage Air Regulator - CGA 346 - 0-60 PSI

Legendary Smith Quality in a High-Purity Package

The Miller Smith 621-01-05-00-00 represents the pinnacle of the Silverline 620 Series, bringing the legendary durability of Smith Equipment (now Miller Electric) to high-purity gas regulation. While Miller is renowned for welding equipment, their gas regulation technology is second to none. This two-stage regulator is built for applications where standard single-stage regulators fall short. By utilizing two stages of pressure reduction, it eliminates the "decay" or rising delivery pressure often seen in single-stage units as the tank pressure drops. This means you can set your pressure to 50 PSI and trust it to stay there until the tank is empty, without constant adjustment.

Built for the Toughest Jobs

Construction quality is immediately apparent in the 620 Series. The regulator body is crafted from nickel-plated brass bar stock, offering superior strength compared to forged bodies found in economy models. This heavy-duty construction ensures the regulator can withstand the rigors of industrial environments while maintaining the delicate precision required for specialty gases. The internal components are equally impressive, featuring a stainless steel diaphragm that provides a high degree of sensitivity and longevity. The metal-to-metal seal design ensures that the regulator remains leak-proof and reliable over years of service.

Versatile and User-Friendly

Designed for ease of use, the regulator features a clear 2-1/2 inch single scale gauge that is easy to read at a glance. The bonnet is threaded front and rear, facilitating panel mounting for integrated system setups. It is specifically configured with a CGA 346 connection for Air service and includes a 1/4" FNPT outlet for easy adaptation to various hose or tubing connections. Whether you are setting up a laser cutting assist gas system, a pneumatic control bench, or a calibration station, the Miller Smith 621-01-05-00-00 delivers the consistent performance backed by the Miller True Blue warranty.
