111-0009 - Miller Smith Silverline General Purpose Inert Gas Regulator, 0-60 PSI, CGA 580

Miller Smith 111-00-09: The Standard for General Purpose Regulation

Welders Supply is proud to offer the Miller Smith 111-00-09 Silverline Series Regulator, a robust single-stage regulator designed for the effective control of inert gases such as Argon, Nitrogen, and CO2. Part of the renowned Silverline family, this unit is tailored for applications where reliable pressure reduction is required, but ultra-high precision (such as in analytical labs) is not necessary. It is the workhorse regulator for welding shops, automotive repair facilities, and maintenance crews looking for quality equipment that lasts.

Built for the Industrial Environment

Durability is at the core of the Silverline design. The regulator features a heavy-duty brass bar stock body that resists mechanical impact and thread damage. To further enhance its longevity, the exterior components—including the bonnet and gauge cases—are plated to resist corrosion and tarnishing. This makes the 111-00-09 particularly well-suited for environments where tools and equipment are exposed to dust, moisture, and rough handling. The unit connects via a standard CGA 580 fitting and includes a 1/4" FNPT outlet, providing flexibility for connecting various hose barbs or adapters depending on your specific setup.

Performance You Can Trust

Consistent pressure delivery is achieved through a substantial 1-7/8" diaphragm, which responds quickly to changes in flow demand. This ensures that your output pressure remains stable within the 0-60 PSIG delivery range, providing the consistency needed for quality welds and effective purging operations. The regulator also incorporates Miller's filtered seat design, known as Sure-Seat technology. By preventing debris from entering the high-pressure seat area, this feature prevents the common "creep" phenomenon where delivery pressure rises when the system is static, ensuring safety and protecting downstream components.

Key Features for Efficiency

• Clear Readability: Dual 2-1/2" gauges provide clear readings of tank pressure and working pressure.
• Versatile Mounting: Includes rear mounting taps for panel installations.
• High Capacity: Rated for inlet pressures up to 3500 PSIG, accommodating modern high-pressure cylinders.

When you need a regulator that balances cost-effectiveness with professional-grade reliability, the Miller Smith 111-00-09 is the clear choice. It delivers the gas control you need for MIG/TIG welding support, pneumatic testing, and general inert gas distribution.
