122-0000 - Miller Smith Silverline 120 Series General Purpose Two-Stage Regulator, 0-100 PSI, 1/4" FNPT

Reliable Gas Flow for Custom Setups and Shop Lines

When your welding or fabrication work depends on a steady flow of shielding gas or purge gas, the Miller Smith 122-00-00 Silverline Regulator delivers the consistency you need. This isn't just a standard cylinder regulator; it's a versatile, two-stage workhorse designed for shops that demand precision. The two-stage design is a game-changer for long-duration jobs. It automatically compensates for the drop in cylinder pressure as you work, meaning you won't have to constantly walk over to the tank to adjust your flow settings. You get a steady, unwavering stream of gas from the start of the tank until it's empty.

The 122-00-00 is built tough with the quality you expect from Miller Smith. The brass body is machined from bar stock—not cast—making it incredibly durable and resistant to shop abuse. The plated finish keeps it looking clean and protects against corrosion. What sets this model apart is its 1/4" FNPT inlet and outlet ports. Instead of being locked into a specific cylinder connection, you have the freedom to adapt this regulator for line usage, custom manifolds, or specific tank setups by simply installing the appropriate fittings. It's perfect for shop air lines, nitrogen purge kits, or central gas distribution systems.

Reading your pressures is effortless thanks to the large, 2-1/2 inch gauges that are easy to see from a distance. The regulator handles up to 100 PSI delivery, covering a wide range of MIG, TIG, and general maintenance applications using Argon, CO2, Nitrogen, or Air. Inside, the Sure-Seat filtered seat technology acts as a first line of defense against dirt and metal shavings, preventing leaks and ensuring your regulator performs flawlessly for years. Whether you are setting up a custom weld station or need reliable pressure control for pneumatic tools, the Silverline 122-00-00 gives you the control and durability professional welders trust.
