Miller Smith 620 Series Silverline High Purity Two-Stage Oxygen Regulator, CGA 540, 0-50 PSI

Precision Control for High Purity Oxygen Applications

When your work demands absolute precision and gas purity, the Miller Smith Silverline 621-02-08-00-00 Two-Stage Regulator is the professional's choice. Designed for laboratory, analytical, and high-end industrial applications, this regulator takes the guesswork out of gas delivery. If you are working with sensitive equipment that cannot tolerate pressure spikes or contamination, this unit provides the stability you need. The two-stage design is a game-changer for long-duration processes; it automatically compensates for the drop in cylinder pressure as your tank empties, meaning you won't have to constantly adjust the knob to maintain your set pressure.

Durability meets performance in the Silverline series. The body is machined from solid brass and nickel-plated, giving it a tough, professional finish that stands up to daily use. Inside, a stainless steel diaphragm replaces the standard rubber components found in cheaper regulators. This means there is no rubber to dry out or absorb contaminants, ensuring that the oxygen flowing to your equipment is as pure as it was in the tank. The regulator also features a high-quality filtered seat that blocks debris, protecting the sensitive internal valve and extending the lifespan of the equipment.

Safety and versatility are built-in. The regulator includes a capturable vent, allowing you to pipe vents away if installed in a confined cabinet or safety-critical area. With a delivery range of 0-60 PSI and a CGA 540 connection, it connects directly to standard oxygen cylinders. Whether you are running a gas chromatograph, a laser system, or a precision welding setup, the Miller Smith 620 Series delivers the consistent, clean flow required for perfect results every time.
