OVERVIEW

Miller Smith Silverline: Durability Meets Precision

For welders and fabricators looking for a dependable general-purpose regulator, the Miller Smith 112-40-09 Silverline Series delivers trusted performance backed by the Miller True Blue promise. This single-stage regulator is designed for applications where reliable flow control is needed for inert gases like Argon and Nitrogen, commonly used in MIG/TIG welding shielding and purging processes. While it is a general-purpose unit, it does not compromise on build quality, featuring a substantial brass bar stock body that feels solid and durable in hand.

Precision control is achieved through a large 1-7/8 inch diaphragm, which provides a sensitive response to pressure adjustments. This ensures that your set delivery pressure remains stable during operation, contributing to consistent weld quality or flow rates. The delivery range of 0-100 PSIG is versatile enough to cover most standard shop needs, from leak testing to shielding gas delivery. The regulator is also tapped for rear panel mounting, offering flexibility for installation on custom carts, manifolds, or workstations.

The 112-40-09 is equipped with Miller's exclusive Sure-Seat filtered seat technology. In the welding environment, where dust and grit are inevitable, this feature is critical. It filters out contaminants before they can damage the high-pressure seat, preventing dangerous pressure creep and extending the lifespan of your equipment. The plated finish on the body and gauges not only looks professional but adds an extra layer of defense against the harsh conditions of a welding shop. Whether you are setting up a new station or replacing an old, worn-out regulator, this Silverline model offers the reliability you expect from Miller Smith.

FAQ

This regulator is designed for inert and non-corrosive gases such as Air, Nitrogen, Helium, and Argon. It comes with a CGA 580 inlet connection.

The delivery pressure range for this specific model is 0-100 PSIG.

No, the Silverline 112-40-09 is a single-stage regulator. It is recommended for applications where extremely precise control of delivery pressure as the cylinder drains is not critical.

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

Yes, it features Miller's Sure-Seat technology, which includes a filtered seat to protect against debris and extend the life of the regulator.

No. This regulator has a CGA 580 connection for inert gases. Oxygen cylinders use a CGA 540 connection, and oxygen service requires specific cleaning and materials to prevent combustion.

The regulator is equipped with large 2-1/2 inch single scale gauges for easy reading.

Yes, the body is tapped to allow for rear panel mounting installations.
