Miller Smith Silverline 312 High Purity Stainless Regulator 100 PSI CGA 660

Uncompromised Quality for Specialty Gas Applications

When your work involves specialty gases, there is no room for error. The Miller Smith Silverline 312 Series Regulator delivers the reliability and precision professionals need when handling high-purity or corrosive elements. Built by one of the most trusted names in gas equipment, this regulator is constructed entirely from 316 stainless steel, ensuring that it stands up to the toughest chemical environments without corroding or contaminating your gas supply. Whether you are working in a research lab, an industrial testing facility, or a specialized welding environment, the Silverline 312 ensures your gas delivery is consistent and safe.

The difference is in the details. The Silverline series moves away from standard rubber components in favor of a stainless steel convoluted diaphragm. This advanced design eliminates the risk of the diaphragm absorbing or releasing contaminants, which is critical for maintaining the strict purity levels required in high-tech applications. It also provides a superior seal, giving you peace of mind that your system is leak-free. The regulator delivers a steady pressure output up to 100 PSIG, easily adjustable to meet the specific needs of your equipment or process.

Safety and ease of use are built right in. The regulator features a captured vent port, allowing you to safely divert any potential leaks away from the workspace—a must-have feature when working with toxic or reactive gases. The large, clear gauges make it simple to monitor your gas levels at a glance, reducing downtime and guesswork. With its robust stainless steel body and thoughtful engineering, the Miller Smith 312-00-25-00-00 is an investment in safety, accuracy, and long-term performance.

Designed for versatility, this unit comes with a CGA 660 connection and standard 1/4" FNPT outlet, making it compatible with a wide range of fittings and hoses. Whether you are panel mounting it for a permanent installation or using it directly on a cylinder, the Silverline 312 is ready to perform. Trust Miller Smith to provide the durability and precision required for your most critical gas delivery challenges.
