320-00000000 - Miller Smith 320 Series High Purity Two-Stage Stainless Steel Regulator, 0-25 PSI

Reliable Control for Specialty Gases

When you are working with specialty gases, standard brass regulators just won't cut it. The Miller Smith 320 Series Two-Stage Regulator is the professional's choice for handling corrosive and high-purity gases with confidence. Built from durable 316 Stainless Steel, this regulator is designed to resist chemical attack and maintain the integrity of your gas supply, ensuring that what comes out of the tank is exactly what goes into your process.

One of the biggest challenges in gas delivery is the "decay" effect—where delivery pressure rises as the cylinder pressure falls. The 320 Series solves this with its two-stage design. By stepping the pressure down in two stages, it delivers a rock-steady flow at your set pressure (up to 25 PSI) from a full tank all the way down to empty. This means you can focus on your work without constantly tweaking the regulator knob.

Built for Safety and Longevity

Miller Smith has packed this unit with features to keep you safe and your equipment running longer. The metal-to-metal diaphragm seal eliminates the use of elastomers that can degrade or leak over time, providing a tight seal you can trust. For those working with hazardous gases, the captured vent ports allow you to pipe vented gas away safely, protecting you and your workspace.

The regulator also features a 316 stainless steel filtered seat, which helps prevent debris from damaging the internal components, extending the life of the regulator. Whether you are setting up a lab, a welding purge station for exotic metals, or a chemical process, the Miller Smith 320 Series gives you the precision and durability you need. It comes ready with 1/4" FNPT connections for easy integration into your manifold or piping system.
