620-03060000 - Miller Smith 620 Series Silverline High Purity Two-Stage Regulator, CGA 350, 0-25 PSI

Reliable Gas Delivery for Professionals

When your work depends on precise gas flow and absolute purity, the Miller Smith 620 Series Silverline Regulator delivers the performance you need. The 620-03-06-00-00 model is a premium two-stage regulator designed to handle high-pressure cylinders up to 3500 PSI while delivering a smooth, consistent low-pressure output of 0-25 PSI. Whether you are working with Hydrogen, Methane, or other gases requiring a CGA 350 connection, this regulator ensures that your equipment receives a steady flow without the pressure spikes or drops common with lesser equipment.

Built for Purity and Durability

The "Silverline" name represents Miller Smith's commitment to quality. This unit features a nickel-plated brass body that not only looks professional but resists corrosion and wear. Inside, a stainless steel diaphragm replaces standard rubber components, ensuring that your gas stream remains uncontaminated by rubber compounds or plasticizers. This makes it an excellent choice for laboratory setups, calibration stations, and high-end manufacturing processes where gas purity is non-negotiable. The large 2-1/2 inch gauges are easy to read, allowing operators to monitor tank levels and delivery pressure at a glance.

Consistent Performance

One of the biggest challenges in gas regulation is "delivery pressure rise"—where the output pressure creeps up as the tank gets empty. The two-stage design of the Miller Smith 620 eliminates this issue completely. By stepping down the pressure twice, it provides a flat, stable output from a full tank down to an empty one. Additionally, the filtered seat design prevents debris from entering the regulator, extending its service life and reducing maintenance downtime. Invest in the Miller Smith 620 Series for a regulator that works as hard and as precisely as you do.
