Miller Smith 320 Series High Purity Stainless Steel Two-Stage Regulator, CGA 350, 0-50 PSI

Reliable Control for Demanding Environments

When your work involves specialty gases like Hydrogen or Methane, you can't rely on standard brass equipment. The Miller Smith 321-00-23-00-00 Two-Stage Stainless Steel Regulator is built to handle the tough stuff. Whether you are working in a lab setting, industrial processing, or specialized fabrication, this regulator delivers the consistent flow and pressure you need to get the job done right, without compromising on safety or durability.

Built Tough with Stainless Steel

Corrosion is the enemy of precision equipment. That's why this Miller Smith regulator is machined from 316 stainless steel bar stock. It stands up to corrosive gases that would eat through lesser materials. The internal components are just as tough, featuring a stainless steel diaphragm and a PCTFE seat. This metal-to-metal construction doesn't just resist corrosion; it ensures a tight seal that keeps your gas pure and your workspace safe from leaks.

Set It and Forget It

One of the biggest headaches with single-stage regulators is the "droop" or rising pressure as your tank gets low. This two-stage model solves that problem completely. It automatically compensates for dropping cylinder pressure, keeping your output at a steady 0-50 PSIG exactly where you set it. This means you don't have to constantly monitor and adjust the knob as you work—saving you time and frustration.

Safety First Features

Dealing with flammable or toxic gases requires extra precautions. This regulator features captured vent ports, allowing you to pipe any potential venting safely away from the operator. It's also built to handle vacuum purging, which is a critical step when swapping out tanks of hazardous gas. With clear 2-1/2" gauges, you can check your levels at a glance. If you need a regulator that works as hard as you do and keeps you safe while doing it, the Miller Smith 320 Series is the professional choice.
