Smith Equipment 820 Silverline High Pressure Oxygen Regulator 0-2000 PSIG

Precision and Durability for High Pressure Jobs

When your work demands reliable gas control at high pressures, the Miller Smith 825-66-08 Silverline Regulator delivers the performance you need. Designed for professionals who handle specialty gases, testing rigs, and calibration duties, this regulator takes the guesswork out of high-pressure management. Unlike standard regulators that might struggle with extreme inlet pressures, the Silverline 820 series uses a heavy-duty piston sensor. This design ensures that the regulator can safely handle up to 6000 PSI coming from the cylinder while delivering a smooth, consistent output up to 2000 PSI.

Durability is built into every inch of this tool. The solid brass construction is coated in a tough nickel plating, protecting your investment from corrosion and wear in harsh industrial environments or busy workshops. Whether you are purging systems, charging accumulators, or running high-pressure tests, the corrosion-resistant finish keeps the regulator looking and functioning like new for years. The large 2-1/2 inch gauges are easy to read from a distance, reducing eye strain and helping you monitor your gas supply accurately without constantly stepping up to the tank.

Ease of use is a standout feature of the 825-66-08. The adjusting knob is engineered for low-torque operation, meaning you can dial in your exact pressure requirements smoothly without fighting the mechanism. It also features a self-relieving screw, which is a huge benefit when you need to lower the pressure in a closed system—the regulator automatically vents the excess pressure as you back off the knob. Cleaned for oxygen service and equipped with a CGA 540 connection, this regulator is ready for critical tasks right out of the box, providing the safety and reliability Miller Smith is known for.
