321-83220000 - Miller Smith 320 Silverline High Purity Stainless Steel Regulator, CGA 330, 50 PSI

Reliable Gas Delivery for Specialty Welding and Labs

When your work involves corrosive gases or requires absolute purity, standard equipment simply won't cut it. The Miller Smith 321-83-22-00-00 High Purity Two-Stage Regulator is the professional's choice for managing specialty gases with confidence. Part of the renowned 320 Silverline Series, this regulator is built to deliver consistent performance in the most demanding industrial and laboratory environments. The two-stage design is a game-changer for long-duration processes, as it automatically compensates for the drop in cylinder pressure as the tank empties, giving you a steady 0-50 PSI output without the need for constant manual adjustment.

Built to Last in Harsh Environments

Corrosion is the enemy of precision, which is why this Miller Smith regulator is constructed almost entirely from 316 Stainless Steel. From the bar stock body to the convoluted diaphragm, the use of high-grade stainless steel ensures that the regulator resists attack from corrosive gases, preventing premature failure and contamination of your process. The large, 2-1/2 inch single-scale gauges are easy to read at a glance, allowing you to monitor tank levels and delivery pressure accurately. Whether you are setting up a laser mix, an analytical instrument, or a specialized welding shield gas, the reliability of the 321-83-22-00-00 is unmatched.

Designed for Operator Safety

Handling specialty gases often means dealing with hazardous substances. This regulator incorporates thoughtful safety features like captured vent ports, which allow you to pipe potential leaks away from the workspace. It is also engineered to handle the vacuum cycles used during purging, ensuring that no atmospheric air contaminates your lines when swapping cylinders. With its panel-mountable design and standard CGA 330 connection, it integrates seamlessly into professional gas cabinets and workstations.
