OVERVIEW

Reliable Air Regulation for Professionals

When your work demands consistency, the Miller Smith 121-20-10 Silverline Series Regulator delivers. This general-purpose two-stage regulator is the go-to solution for professionals using Industrial Air (CGA 590) who cannot afford pressure drops or fluctuations. Whether you are running pneumatic tools, calibrating equipment in a lab, or managing general plant maintenance, the two-stage mechanism ensures that your output pressure remains rock-steady from the moment you open a full cylinder until it is time to swap it out. Say goodbye to the constant readjustments required by single-stage regulators.

Built Tough for the Shop

Miller knows that shop environments are tough on equipment. That is why the Silverline series is constructed from solid brass bar stock, not cheap castings. This heavy-duty build is complemented by a plated finish that resists corrosion and keeps your gear looking professional. The 121-20-10 is designed with longevity in mind, featuring a filtered seat that blocks dirt and contaminants from damaging the internal components. This means fewer repairs, less downtime, and a better return on your investment.

User-Friendly Features

Accuracy is everything. This regulator features a large 1-7/8 inch diaphragm that provides smooth, precise control over the 0-50 PSI delivery range. The oversized 2-1/2 inch gauges are clear and easy to read, even from a distance, helping you monitor your gas supply effectively. The body is also tapped for rear panel mounting, giving you flexible installation options for custom workbenches or gas manifolds. Trust Miller Smith for quality, safety, and performance in every job.

  • Consistent Flow: Two-stage design eliminates delivery pressure decay.
  • Industrial Ready: CGA 590 connection for Industrial Air cylinders.
  • Long Life: Filtered seat technology protects against contamination.

FAQ

A single-stage regulator reduces cylinder pressure to delivery pressure in one step, which can cause delivery pressure to rise as the cylinder empties. A two-stage regulator reduces pressure in two steps, providing a constant delivery pressure regardless of the cylinder pressure level.

The CGA 590 connection is standard for Industrial Air and Sulfur Hexafluoride. It is not compatible with standard Inert Gas fittings like CGA 580 (Argon/Nitrogen/Helium).

No, this regulator is equipped with a CGA 590 connection and is designed for Industrial Air. Oxygen cylinders use CGA 540 connections. Never use oil or incompatible regulators with Oxygen due to explosion hazards.

The maximum inlet pressure for this regulator is 3500 PSIG.

Yes, Miller Smith equipment typically comes with the True Blue Warranty. Please check the specific warranty documentation included with the product for duration and coverage details.

Yes, the delivery pressure is adjustable within the range of approximately 0-50 PSIG (gauges may read 0-60 or 0-100 depending on the specific gauge batch, but the control range is designed for low pressure applications).

Yes, the body of the Silverline series regulators is tapped to allow for rear panel mounting.
