OVERVIEW

Reliable Precision for the Pros

When your work demands more than just a standard industrial regulator, the Miller Smith 212-20-05 Silverline series steps up to the plate. This isn't your average shop regulator; it is a high-purity instrument designed for professionals who need clean, consistent air delivery without compromise. Whether you are setting up a test bench, running pneumatic instruments, or managing gas delivery in a clean environment, this regulator delivers the reliability Miller Smith is famous for. The CGA 346 connection is specifically designed for compressed air, ensuring you never accidentally connect the wrong gas source.

Durability is built into every inch of this unit. The body is machined from solid brass bar stock—no cheap castings here—and then fully plated. This plating isn't just for looks; it protects the regulator from oxidation and keeps it looking new even after years of service. The gauges are large (2-1/2 inches) and easy to read at a glance, so you aren't squinting to check your pressures. Inside, a stainless steel diaphragm replaces the standard rubber ones found in cheaper units. This means you get snappier response times, better pressure holding, and no rubber smell or contamination in your air line.

The 212-20-05 is designed to handle up to 3500 PSI inlet pressure and delivers a smooth, adjustable output up to 100 PSI. It also features a filtered seat to keep debris out of the sealing mechanism, which is the number one cause of regulator failure. If you are looking for a regulator that combines the toughness of industrial equipment with the precision of laboratory gear, the Silverline 210 series is the tool for the job. It's built to last, built to perform, and backed by the quality assurance of Miller Smith.

FAQ

CGA 346 is the standard connection for compressed air (industrial or breathing) for pressures up to 3000 PSI (sometimes rated higher depending on the cylinder).

A stainless steel diaphragm is non-permeable and does not off-gas like rubber diaphragms, ensuring the gas stream remains pure and uncontaminated for analytical applications.

No, this regulator has a CGA 346 fitting for Air. Oxygen cylinders use CGA 540. You should never use an adapter to force a connection due to safety risks.

The regulator is rated for a maximum inlet pressure of 3500 PSI.

No, the Miller Smith 212-20-05 is a single-stage regulator. It is best suited for applications where a constant delivery pressure is not critical as the cylinder drains, or where the source pressure is regulated upstream.

This specific model is calibrated for a delivery pressure range of 0-100 PSI.

No, the body is constructed from brass bar stock that has been plated. It is suitable for non-corrosive gases but not for corrosive applications requiring full stainless steel construction.

Yes, the body is tapped to accommodate rear panel mounting, making it ideal for fixed installations.
