120-8407 - Miller Smith Silverline 2-Stage Acetylene Regulator CGA 510

Reliable Flame Stability for Professional Welders

When you are in the middle of a cut or a weld, the last thing you want to worry about is your flame changing as your tank gets low. The Miller Smith 120-84-07 Silverline Series Regulator solves this problem with its premium two-stage architecture. Unlike single-stage regulators that allow delivery pressure to rise as the cylinder empties, this two-stage workhorse keeps your output pressure rock-steady from a full tank down to the bottom. This means less time adjusting knobs and more time working.

Designed specifically for fuel gas applications requiring a CGA 510 connection, this regulator is capped at 15 PSI delivery to ensure safe operation with Acetylene. The heavy-duty plated brass body can take the knocks and bumps of a busy shop, while the nickel-plated bonnet adds an extra layer of protection. The large 2-1/2 inch gauges are clear and easy to read, even from a distance, so you always know your status at a glance.

Inside, Miller Smith's filtered seat technology protects the vital internal components from contamination, a common cause of regulator failure. The 9/16-18 Left Hand outlet thread ensures compatibility with standard fuel gas hoses. Whether you are setting up a stationary manifold system or outfitting a heavy-duty portable rig, the 120-84-07 delivers the reliability and precision Miller Smith is famous for.
