120-8208 - Miller Smith Silverline 120 Series Two-Stage Oxygen Regulator, 0-15 PSI

Precision Gas Control for Analytical Applications

The Miller Smith 120-82-08 Silverline Series General Purpose Two Stage Regulator is engineered for environments demanding high-precision gas delivery and unwavering stability. As part of the renowned Silverline 120 Series, this regulator features a sophisticated two-stage design that effectively isolates the delivery pressure from fluctuations in the inlet supply. This means that as your oxygen cylinder pressure decays from a full 3500 PSIG down to empty, the outlet pressure remains constant at your set point, eliminating the need for frequent manual adjustments common with single-stage alternatives.

Constructed from rugged brass bar stock, the body and bonnet are finished with a durable plating that resists corrosion and wear, making it suitable for both laboratory settings and general plant maintenance. The heart of the regulator is its large 1-7/8 inch diaphragm, which provides exceptional sensitivity and response to flow changes, ensuring precise control within the 0-15 PSIG delivery range. This specific model is configured with a CGA 540 inlet for Oxygen service and a standard 9/16"-18 Right Hand outlet, ensuring compatibility with standard oxygen hoses and equipment.

Reliability is further enhanced by Miller's proprietary Sure-Seat technology. This filtered seat design prevents debris and particulate matter from entering the high-pressure seat area, a common cause of regulator failure and creep. The unit also features large, 2-1/2 inch single-scale gauges that are easy to read from a distance, and the body is tapped to facilitate rear panel mounting if required. For applications where inboard diffusion of air must be minimized, the solid construction and high-quality seals provide the necessary integrity for general purpose non-corrosive gas control.
