112-4002 - Miller Smith Silverline 112 Series Single Stage CO2 Regulator, 0-100 PSI, CGA 320

Reliable CO2 Pressure Control for Industrial Use

The Miller Smith 112-40-02 is a workhorse regulator designed to deliver consistent performance for welders and fabricators utilizing Carbon Dioxide (CO2). Whether you are setting up a shielding gas supply for flux-cored arc welding or powering pneumatic tools, this single-stage regulator provides the control you need. With a delivery pressure range of 0-100 PSIG, it covers a broad spectrum of workshop requirements. The regulator connects directly to standard CO2 cylinders via a CGA 320 fitting, ensuring a secure and leak-free seal.

Durability is a standout feature of the Silverline Series. The regulator is built from solid brass bar stock, providing a heavy-duty foundation that resists deformation and impact. Miller takes this a step further by plating the exterior components, including the body and bonnet, to offer superior protection against the harsh conditions often found in welding shops and industrial sites. The inclusion of Sure-Seat technology means the regulator is designed to resist seat degradation, a common issue that leads to pressure creep and equipment failure.

Operation is straightforward thanks to the large 2-1/2 inch single scale gauges that allow operators to monitor cylinder and delivery pressure at a glance. The 1-7/8 inch diaphragm ensures that flow remains relatively stable even as cylinder pressure decays. For users needing a dependable, no-nonsense regulator that balances cost with professional-grade construction, the Miller Smith 112-40-02 is an excellent selection. It comes backed by Miller's reputation for quality in gas equipment.
