When your work depends on a steady supply of air, the Miller Smith 122-20-05 Silverline Regulator is the tool you can trust to simply work, day in and day out. Designed for general purpose applications in maintenance shops, fabrication floors, and industrial plants, this regulator takes the headache out of gas management. The "Two-Stage" feature is the real hero here: it means you can set your pressure once and forget it. With cheaper single-stage regulators, you often have to keep tweaking the knob as your tank gets low to prevent pressure spikes. The 122-20-05 eliminates that hassle, keeping your output locked at your desired setting (up to 100 PSI) from a full tank all the way down to empty.
Built to survive the rough environment of a working shop, this regulator features a solid brass body that is machined from bar stock—not cheap cast metal. It feels heavy and substantial in the hand, and the plated finish helps it shrug off grime and corrosion. The gauges are large (2-1/2 inches) and easy to read from a distance, so you can check your levels with a quick glance. It comes ready to connect to standard Air cylinders with a CGA 346 fitting, and the outlet features a needle valve for precise on-the-fly flow adjustments.
Safety and longevity are built-in. The Sure-Seat filtered seat technology keeps dirt and particles from ruining the internal seals, which is a common cause of regulator failure. A preset safety relief valve vents to the atmosphere if pressure gets too high, adding an extra layer of protection for you and your equipment. Whether you are running pneumatic tools, purging lines, or supplying air for a specialized process, this Miller Smith regulator offers the professional-grade performance that welders and tradespeople expect from the Miller brand.
