620-01020002 - Miller Smith 620 Series High Purity Two-Stage CO2 Regulator, 0-25 PSI

Reliable CO2 Delivery for Professional Setups

When your work demands absolute consistency, the Miller Smith 620 Series Silverline Regulator delivers. This isn't your average shop regulator; it is a high-performance tool designed to take the guesswork out of gas delivery. Built with a CGA 320 connection, it connects directly to standard Carbon Dioxide cylinders, providing a rock-steady flow for your welding, beverage, or laboratory needs. The standout feature here is the two-stage mechanism. If you've ever had to constantly tweak your regulator knob as your tank gets low, you know the frustration of single-stage drift. This unit solves that problem completely, maintaining your set pressure of 0-25 PSIG perfectly steady until the tank is practically empty.

Built to Last

Durability is key in any equipment, and Miller Smith doesn't cut corners. The regulator body is crafted from solid brass and nickel-plated to resist corrosion and wear. It looks professional and stays that way. The large 2-1/2 inch gauges are easy to read at a glance, allowing you to monitor both your tank level and your delivery pressure without squinting. The outlet is a standard 1/4" FNPT, giving you the flexibility to adapt to various hose fittings or hard lines depending on your specific setup.

High Purity Performance

While it's tough enough for the shop, this regulator has the heart of a laboratory instrument. It features a stainless steel diaphragm instead of the rubber ones found in cheaper units. This means it won't degrade over time or contaminate your gas stream. Whether you are running a precision TIG setup that requires ultra-pure shielding gas or a specialized CO2 application, the 620 Series ensures that what comes out of the nozzle is exactly what came out of the tank. It also handles vacuum purging, making it versatile for complex system setups.
