623-42100000 - Miller Smith Silverline 2-Stage High Purity Regulator CGA 590 250 PSI

Reliable Two-Stage Gas Control

The Miller Smith 623-42-10-00-00 is a premium two-stage regulator designed for professionals who require consistent performance and durability. Belonging to the Silverline 620 Series, this regulator is built to handle high-pressure cylinders up to 3500 PSI while delivering a precise, steady outlet pressure of up to 250 PSI. The two-stage design is a significant advantage over single-stage models; by reducing pressure in two steps, it maintains your set delivery pressure automatically, even as the tank pressure drops significantly during use. This eliminates the need for frequent manual adjustments and ensures your equipment receives a steady flow of gas.

Construction quality is paramount in the Miller Smith line. This unit features a body machined from solid brass bar stock, which is then nickel-plated to protect against environmental corrosion and wear. The internal components are equally robust, featuring a stainless steel diaphragm that provides superior sensitivity and longevity compared to rubber alternatives. The stainless steel diaphragm also allows for a metal-to-metal seal, reducing leak points and maintenance requirements. A 316 stainless steel filter is integrated into the seat assembly to trap any debris from the cylinder, protecting the internal valve mechanism from damage and extending the regulator's operational life.

This specific model is configured with a CGA 590 inlet connection, typically used for Industrial Air and certain specialty gases. It includes large, easy-to-read 2-1/2 inch single scale gauges that allow operators to monitor tank and delivery pressure at a glance. For added utility, it comes with a 1/8" tube stainless steel needle valve on the outlet, giving you immediate and precise control over gas flow. Whether for industrial maintenance, specialized fabrication, or testing applications, the Miller Smith 623-42-10-00-00 delivers the reliability and precision associated with the Miller name.
