321-70210000 - Miller Smith 320 Series High Purity Stainless Steel Regulator CGA 326

Reliable Control for Tough Gases

When you are dealing with specialty gases that can eat through standard equipment, you need a regulator built to survive. The Miller Smith 320 Series High Purity Regulator is the answer for welders and technicians handling corrosive or high-purity mixtures. Built with a solid 316 stainless steel body and internals, this regulator stands up to harsh chemical environments that would destroy brass alternatives. It’s not just about durability; it’s about keeping your gas stream pure and your results consistent.

This is a two-stage regulator, which means it does the heavy lifting for you. As your tank drains and pressure drops, a single-stage regulator would let the delivery pressure climb, forcing you to constantly tweak the knob. This Miller Smith unit maintains a steady 0-50 PSIG output from start to finish, letting you focus on the job rather than the gauge. The stainless steel diaphragm is convoluted for extra sensitivity, giving you fine-tuned control over your flow.

Safety is built right in. The regulator features captured vent ports, allowing you to pipe hazardous fumes away safely if a leak ever occurs. The gauges are large and easy to read, and the metal-to-metal seals ensure a tight system. Whether you are setting up a lab process, a laser mix, or a specialized welding application requiring a CGA 326 connection, this regulator delivers the professional performance and reliability Miller is known for.
