120-0000 - Miller Smith Silverline 120 Series Two-Stage General Purpose Regulator, 0-30 PSI, 1/4" FNPT

Reliable Gas Flow for Shop and Maintenance

In the demanding environment of a welding shop or maintenance facility, consistency is key. The Miller Smith 120 Series Silverline Regulator delivers exactly that, thanks to its robust two-stage design. For fabricators and maintenance teams, the "set it and forget it" capability of a two-stage regulator is a major productivity booster. As your gas tank empties, a standard regulator often requires you to constantly tweak the pressure knob to prevent flow spikes. The 120-00-00 eliminates this hassle by automatically compensating for the dropping tank pressure, providing a steady 0-30 PSI flow from a full tank down to the last few pounds.

Built to withstand the rigors of daily industrial use, this regulator features a body machined from rugged brass bar stock. This construction method results in a denser, stronger tool that resists damage from accidental knocks better than cast regulators. The bright plated finish helps keep the unit looking clean and resists corrosion in humid shop environments. The large, 2-1/2 inch single-scale gauges are easy to read at a glance, ensuring you can monitor your system status without squinting. Whether you are setting up a purge line for stainless steel welding or powering pneumatic testing equipment, the clear readout and smooth adjustment knob make operation intuitive.

Versatility is another strong point of this general-purpose model. Instead of a fixed tank connection, it comes with 1/4" FNPT female threads on both the inlet and outlet. This allows you to adapt the regulator to virtually any setup—whether you need to connect it to a hard-piped shop air line, a custom manifold, or a standard cylinder using a separate CGA nipple. Compatible with Argon, CO2, Nitrogen, and Air, the Miller Smith 120-00-00 is a versatile utility player for your gas equipment arsenal, backed by Sure-Seat technology that filters out dirt to keep your equipment running longer with less maintenance.
