Miller Smith Silverline 620 Series 2-Stage High Purity CO2 Regulator, 0-250 PSI

Reliable CO2 Delivery for Critical Operations

When your operation requires absolute consistency and reliability in gas delivery, the Miller Smith 623-01-02-00-00 Silverline Regulator is the professional's choice. While often used in laboratory settings, this high-purity two-stage regulator is also excellent for specialized industrial applications where standard welding regulators may fall short on precision. Built for Carbon Dioxide (CO2) service with a CGA 320 connection, it offers a delivery pressure up to 250 PSI, making it versatile for various pneumatic and process control tasks.

The two-stage design is a significant advantage for long-duration tasks. It automatically compensates for the drop in cylinder pressure as you consume gas, meaning you won't have to constantly adjust the regulator knob to maintain your set pressure. This "set it and forget it" capability improves efficiency and process consistency. The regulator features large, easy-to-read 2-1/2 inch single scale gauges, allowing operators to monitor tank and delivery pressure at a glance.

Durability is built into every component. The body is machined from solid brass bar stock and nickel-plated for superior toughness and resistance to environmental corrosion. The internal diaphragm is made from 316 stainless steel, providing a much longer service life than standard rubber diaphragms, especially when exposed to temperature fluctuations or long storage periods. The regulator also features threaded front and rear bonnets for easy panel mounting if required. Whether for a custom fabrication setup, a laser system, or a testing bench, this Miller Smith regulator delivers the performance and safety features required by top-tier professionals.
