OVERVIEW

Reliable Control for Corrosive Environments

When your work involves specialty gases or corrosive environments, standard brass regulators simply won't cut it. The Miller Smith 320 Series High Purity Two-Stage Regulator is built to handle the tough stuff. Designed with a body and wetted parts made from 316 Stainless Steel, this regulator stands up to corrosive gases like ammonia (CGA 705) without degrading, ensuring your equipment lasts longer and your gas supply remains pure. Whether you are working in a lab setting, industrial chemical processing, or specialized welding applications, this regulator delivers the reliability you need.

Consistent Pressure, Every Time
One of the biggest challenges with gas cylinders is the "droop" in pressure as the tank empties. This Miller Smith regulator features a two-stage design that automatically compensates for dropping cylinder pressure, giving you a steady 0-50 PSI output from start to finish. You won't have to constantly adjust the knob to maintain the correct flow. The large, easy-to-read 2-1/2 inch gauges allow you to monitor tank levels and delivery pressure at a glance, keeping your operation running smoothly.

Safety First Design
Handling hazardous gases requires equipment that prioritizes safety. This regulator includes a captured vent port, allowing you to pipe any potential leaks away from the workspace, protecting you and your team. The metal-to-metal diaphragm seal ensures a tight, leak-proof connection, while the robust stainless steel construction resists wear and tear. If you need a regulator that combines high-performance precision with industrial-grade durability, the Miller Smith 320 Series is the professional choice.
