220-2000 - Miller Smith 220 Series Silverline High Purity Two-Stage Regulator, 0-15 PSI, 1/4" FNPT

Reliable High Purity Gas Regulation

When your work demands absolute precision and cleanliness, the Miller Smith 220-20-00 Silverline Regulator is the professional's choice. This high-purity, two-stage regulator is built to handle the delicate requirements of specialty gas delivery without sacrificing the ruggedness expected from Miller equipment. Whether you are managing carrier gases for a lab or setting up a precise calibration station, this regulator delivers consistent performance you can trust.

The standout feature of the 220-20-00 is its two-stage architecture. Unlike single-stage regulators that can see outlet pressure rise as the tank gets low, this unit maintains a rock-steady 0-15 PSI flow from a full cylinder down to an empty one. This consistency is critical for preventing instrument drift and ensuring accurate readings. The internal components are protected by a filtered seat, which stops debris from causing leaks or creep, a common issue in less advanced regulators.

Constructed from brass bar stock and finished with a durable plating, the regulator body is tough enough for industrial environments while remaining clean enough for analytical use. The stainless steel diaphragm is a key upgrade over standard models, offering superior sensitivity and ensuring that the regulator itself does not add contaminants to your pure gas stream. Large, easy-to-read 2-1/2 inch gauges allow for quick monitoring of tank and line pressure. With 1/4" FNPT connections, this unit is versatile and ready to be adapted to your specific manifold or tubing requirements.
