254-8202 - Miller Smith 250 Series Silverline High Purity CO2 Regulator 0-200 PSI

Miller Smith 250 Series Silverline Regulator - 254-82-02

For professional welders and industrial gas specialists requiring precise control over liquid cylinder gas delivery, the Miller Smith 254-82-02 Silverline Regulator stands out as a top-tier performer. This single-stage regulator is built to handle the rigors of industrial environments while delivering the high purity required for analytical work. With a delivery range of 0-200 PSIG and a maximum inlet pressure of 3500 PSIG, it is robust enough for bulk gas distribution yet sensitive enough for laboratory use.

The 254-82-02 is distinctively designed with a rear-entry (back mount) CGA 320 connection. This configuration is optimized for liquid cylinders, allowing the regulator to sit flush and secure, reducing the leverage and torque often applied to standard side-entry regulators when mounted on dewars. The regulator controls the delivery of gas—not liquid—making it a critical component in systems where consistent gas phase withdrawal is required from a cryogenic source. The use of a 1-7/8 inch stainless steel diaphragm provides exceptional sensitivity and pressure stability, ensuring that your flow rates remain constant even as the cylinder pressure fluctuates.

Durability is a key characteristic of the Silverline series. The regulator is machined from rugged brass bar stock and finished with a heavy nickel plating. This not only gives it a professional appearance but also protects the exterior from atmospheric corrosion and wear. The internal components are equally robust, featuring the Sure-Seat™ filtered seat assembly. This proprietary design filters out debris that could damage the seat, significantly extending the service life of the regulator and ensuring a leak-tight seal over time.

Visibility and ease of use are also addressed with large 2-1/2 inch gauges. These gauges feature high-contrast faces that make checking tank levels and output pressure simple, even in dimly lit shops or crowded gas storage areas. Whether you are setting up a laser cutting station, a laboratory analyzer, or a specialized welding application requiring pure CO2, the Miller Smith 254-82-02 offers the reliability and precision you need to get the job done right.
