1424-0408 - Victor 2-Inch High Pressure Regulator Gauge 4000 PSI

Keep Your Regulator Reading Right

There is nothing more frustrating—or potentially unsafe—than a regulator with a busted gauge. Whether it took a hit from a falling piece of steel or just clouded over from years of shop grime, a reliable high-pressure gauge is the only way to know how much gas you have left in the tank. The Victor 1424-0408 is the standard 2-inch replacement gauge for the high-pressure side of your regulator, reading up to 4000 PSI. It’s the gauge that tells you if you have enough Oxygen or Argon to finish the job or if you need to swap cylinders before you strike an arc.

This isn't a cheap generic knock-off; it's a genuine Victor component. That means it threads perfectly into your Victor SR 450, SR 250, or similar heavy-duty regulators without cross-threading or leaking (always use approved Teflon tape or paste for gas service). The dial is clear and easy to read, with a dual scale that shows both PSI and kPa, so you don't have to do mental math if your shop specs are in metric. The 50mm size is the "standard" size for most industrial regulators—big enough to read easily, but not so big that it gets in the way or snaps off easily.

Installation is straightforward for any welder with a wrench. Simply depressurize your system, remove the old gauge, clean the threads, apply a small amount of oxygen-safe sealant to the new gauge threads, and screw it in. Having a working high-pressure gauge prevents the dreaded "mid-weld empty tank" scenario. It also helps you spot leaks; if you close the cylinder valve and the needle drops, you know you have a leak somewhere in the system. Keep your gear in top shape and your welds consistent with this durable brass replacement gauge.
