When your regulator gauge gets smashed or stops reading accurately, you need a replacement that can handle the shop environment. The Smith Equipment GA137-03 is a tough, 2-inch replacement gauge designed specifically for the delivery side of your regulator. With a range of 0-150 PSI (and 0-10 Bar), it's perfect for monitoring output pressure on Oxygen, Argon, CO2, and other inert gas setups.
Built Tough for Welders
We know tools take a beating. That's why this gauge ditches the fragile glass for a shatter-proof polycarbonate crystal. It won't crack if a wrench slips or a cable swings into it. The steel case adds another layer of protection, and the "twist-on" crystal ring design keeps everything sealed and secure. It's built to last through daily use in fabrication shops, construction sites, and garages.
Precision You Can Trust
Guesswork leads to bad welds. This gauge uses a precision watch-type movement to give you smooth, accurate readings every time you adjust your flow. The high-contrast dial is easy to read even through a welding helmet or in low-light corners of the shop. It connects via a standard 1/4" NPT thread, so it fits not just Smith regulators, but almost any major brand regulator you have on your bottles.
Don't let a broken gauge slow you down. Swap it out with a genuine Smith replacement and get back to laying beads with confidence.
