Miller Smith 320 Series High Purity Stainless Steel Two-Stage Regulator, CGA 660, 0-25 PSI

Reliable High Purity Gas Regulation

When your work involves specialty gases, precision and safety are not optional—they are requirements. The Miller Smith 320 Series High Purity Stainless Steel Regulator delivers the reliability you need for handling corrosive and high-purity gases. Built by one of the most trusted names in the industry, this regulator is part of the Silverline series, designed to offer top-tier performance in laboratory and industrial settings. With a delivery pressure range of 0-25 PSI and a maximum inlet pressure of 3500 PSI, it is perfectly suited for sensitive applications where stable pressure is critical.

The 320-85-25-00-00 model stands out with its robust stainless steel construction. Every wetted part, including the body and diaphragm, is made from 316 stainless steel or PCTFE, ensuring that the regulator resists corrosion and maintains the integrity of your gas supply. This is especially important when using the CGA 660 connection for corrosive gases, as standard brass regulators would quickly degrade. The two-stage design is a favorite among professionals because it eliminates the need for constant adjustment; as your tank pressure drops, your output pressure stays rock-steady, letting you focus on your work rather than your equipment.

Safety and ease of use are built into every aspect of this regulator. The large 2-1/2 inch gauges provide clear, immediate readings of both tank and delivery pressure. For environments handling hazardous fumes, the captured vent ports allow you to pipe vented gases away safely, protecting you and your workspace. Whether you are setting up a new chromatography station or managing process gases in a manufacturing facility, the Miller Smith 320 Series offers the durability and precision you can trust. Backed by the quality assurance of Miller, this regulator is an investment in safety and accuracy.
