623-00100000 - Miller Smith Silverline 620 Series High Purity 2-Stage Regulator, CGA 590, 250 PSI

Reliable Gas Delivery You Can Trust

When your work demands precision and consistency, the Miller Smith 623 Series Silverline Regulator delivers. This two-stage high-purity regulator is built to handle the toughest jobs while maintaining a steady flow. If you are working with specialty gases using a CGA 590 connection, this regulator ensures that your output pressure stays locked at your set point—up to 250 PSI—even as your tank pressure drops. No more constant adjusting or worrying about flame fluctuation or flow variance; the two-stage mechanism does the heavy lifting for you.

Durability is key in any industrial environment, and the Silverline 620 series is constructed from nickel-plated brass to resist corrosion and wear. The internal components are just as tough, featuring a stainless steel diaphragm that offers superior service life compared to traditional rubber components. This metal diaphragm also provides a "high purity" seal, meaning it won't contaminate your gas stream, which is vital for sensitive welding, testing, or laboratory applications. The large 2-1/2 inch gauge makes reading your pressure settings easy, even from a distance.

Safety is never an afterthought with Miller Smith equipment. This model features captured vents, allowing you to pipe emissions away safely if necessary, and a filtered seat to stop debris from causing leaks or failures. Whether you are setting up a test bench, a specialized welding station, or a laboratory gas manifold, the 623-00-10-00-00 offers the professional-grade reliability and safety features that welders and tradespeople expect from the Miller brand. Mount it directly to the cylinder or panel-mount it for a permanent installation; this regulator is ready to perform.
