When your work involves specialty gases that are corrosive or require absolute purity, standard brass regulators simply won't cut it. The Miller Smith 320 Series High Purity Two-Stage Regulator is the professional's choice for managing difficult gases with confidence. This specific model, the 322-68-25-00-00, comes equipped with a CGA 660 connection and is rated for delivery pressures up to 100 PSI. Whether you are setting up a process analyzer, managing laser gases, or working in a chemical lab, this regulator provides the consistency and safety you need.
Corrosion is the enemy of precision equipment. That is why this regulator is built from 316 Stainless Steel. Unlike brass, which can react with certain gases and contaminate your process or fail prematurely, stainless steel stands up to aggressive chemical properties. The internal seat is also filtered to prevent debris from causing leaks or pressure creep. If you are working with gases that demand a CGA 660 fitting, you likely know the risks involved; this regulator mitigates those risks with a robust metal-to-metal seal design that ensures what stays in the regulator belongs there.
One of the biggest headaches in gas delivery is the "droop" or pressure spike that happens as a tank gets low. Because this is a two-stage regulator, it steps the pressure down twice before it reaches your equipment. This means that even if your tank pressure swings from 3500 PSI down to 500 PSI, your outlet pressure stays rock solid at your set point. You won't have to constantly adjust the knob to maintain flow.
Miller Smith has designed this unit with the operator's safety in mind. It features large, 2-1/2 inch gauges that are easy to read from a distance, so you always know your system status. More importantly, it includes captured vent ports. If a diaphragm were ever to fail, the gas wouldn't just vent into the room; the threaded ports allow you to pipe any escaping gas to a safe exhaust system. This feature is essential for maintaining a safe workspace when dealing with hazardous or toxic fumes.
