120-8408 - Miller Smith Silverline 120 Series Two-Stage Inert Gas Regulator, 0-30 PSI

Precision Control for Laboratory and General Purpose Applications

The Miller Smith 120-84-08 Silverline Series General Purpose Two-Stage Regulator is engineered for professionals requiring precise pressure control and unwavering reliability. Designed to handle inert and non-corrosive gases such as Air, Nitrogen, CO2, and Argon, this regulator is a staple in laboratories, testing facilities, and general maintenance shops. The two-stage architecture is the defining feature of the 120 Series, reducing cylinder pressure in two steps to ensure that the delivery pressure remains constant, even as the inlet pressure drops during cylinder depletion. This eliminates the need for frequent manual adjustments, allowing operators to focus on their critical tasks.

Constructed from rugged brass bar stock, the body is built to withstand the rigors of industrial environments while maintaining the precision required for analytical work. The entire assembly—including the body, bonnet, and gauges—is nickel-plated. This plating not only enhances the aesthetic appeal but provides superior protection against corrosion and wear, ensuring the unit remains clean and functional over a long service life. The regulator features a large 1-7/8 inch diaphragm which is highly sensitive to pressure changes, affording the user fine-tuned control over the 0-30 PSIG delivery range.

Internal components are protected by Miller Smith's Sure-Seat technology. A filtered seat prevents debris and particulate matter from entering the high-pressure seat assembly, a common cause of regulator failure. This design significantly extends the service life of the regulator and maintains the purity of the gas stream, which is critical for sensitive applications. The unit comes equipped with large, easy-to-read 2-1/2 inch single scale gauges and is tapped for rear panel mounting, offering versatile installation options for custom benches or equipment racks.
