Miller Smith 820 Silverline High Pressure Regulator, 0-4000 PSI, CGA 347

Heavy-Duty High Pressure Regulator for Industrial Testing

The Miller Smith 826-66-26 Silverline Regulator is a powerhouse tool designed for professionals who require reliable high-pressure gas delivery. Built to handle the toughest jobs, this single-stage regulator features a CGA 347 connection and is capable of delivering pressures up to 4000 PSI. It is an ideal choice for high-pressure testing, chemical plant operations, and manufacturing processes where standard regulators fall short. The unit is 100% tested at maximum rated operating pressure, giving you the confidence that it will perform safely and effectively right out of the box.

Durability is a key feature of the 820 Silverline series. The regulator boasts a nickel-plated body, bonnet, and gauges. This plating process does more than just look good; it provides a hard, protective layer that resists scratches and corrosion, ensuring your equipment remains in top condition for years. The internal piston sensor design is specifically selected for high-pressure service, offering a level of ruggedness that diaphragm-based units cannot match. This makes the 826-66-26 particularly well-suited for applications involving frequent pressure adjustments and high-stress cycles.

User-friendly features abound in this model. The low-torque control adjusting screw makes dialing in specific pressures smooth and effortless, reducing operator fatigue. The large 2-1/2 inch gauges provide clear, instant visual feedback on tank and delivery pressures. Additionally, the body is tapped for rear panel mounting, offering flexible installation options for custom test benches or fixed systems. With its combination of high-pressure capability, robust construction, and precise control, the Miller Smith 826-66-26 is an essential asset for any serious industrial gas setup.
