622-01030000 - Miller Smith Silverline 620 Series High Purity Two-Stage Regulator CGA 326

Reliable Control for Nitrous Oxide Applications

When your work depends on the stable and clean delivery of Nitrous Oxide, the Miller Smith 622-01-03-00-00 Silverline Regulator is the tool you can trust. Designed for professionals who cannot afford pressure spikes or contamination, this two-stage regulator takes the guesswork out of gas management. Whether you are setting up a specialized welding process, a laboratory instrument, or an industrial purging system, the two-stage mechanism ensures that your delivery pressure stays locked at your set point—up to 100 PSI—even as your tank pressure drops. This means you won't have to constantly adjust the knob as the cylinder empties, saving you time and ensuring consistent results.

Durability is built into every inch of this unit. The nickel-plated brass body stands up to the wear and tear of daily shop use, while the stainless steel diaphragm offers superior longevity compared to standard rubber diaphragms. This metal construction is not just about toughness; it's about purity. If your application is sensitive to moisture or hydrocarbons, the metal-to-metal seals and stainless diaphragm prevent the regulator itself from becoming a source of contamination. The CGA 326 fitting is the industry standard for Nitrous Oxide, ensuring a safe and correct connection every time.

Miller Smith has also prioritized safety with the inclusion of a capturable vent. In the unlikely event of a diaphragm failure, gas can be vented safely away via a tube connected to the bonnet, rather than leaking directly into the immediate atmosphere. The large, clear gauges make it simple to check your tank levels and line pressure from a distance. For welders and technicians working with specialty gases, the Silverline 620 series represents the perfect balance of high-end performance and rugged reliability.
