1.5-Inch High Pressure Regulator Gauge 4000 PSI Oxygen/Inert

Keep Your Tank Levels in Check

There is nothing worse than running out of gas in the middle of a perfect bead. The 1.5" High-Pressure Replacement Gauge is your solution for keeping tabs on your shielding gas or oxygen supply. Rated for 4000 PSI, this gauge is designed to screw into the "Inlet" or high-pressure side of your regulator, telling you exactly how much pressure is left in your tank. Whether you are running pure Argon for TIG, C25 for MIG, or Oxygen for cutting, this gauge gives you the info you need at a glance.

Regulator gauges take a beating. They get smashed by falling objects, cracked during transport, or just wear out over time. This replacement unit features a 1.5-inch face, which is the standard size for many compact flowmeters and regulators found on portable welders. It uses a 1/8" NPT thread, which is the industry standard connection. Installation is simple: just remove the old broken gauge, apply the correct Teflon tape (make sure it's rated for the gas you are using!), and screw this one in.

Safety First: This gauge is cleaned for oxygen service right out of the box. This means it's safe to use on Oxygen tanks as well as Inert gases like Argon, Helium, and Nitrogen. Don't risk using a dirty or oil-contaminated gauge on an oxygen line. Stick with a gauge that is built for the job. The clear markings allow you to see your pressure level instantly, so you know when it's time to swap out that cylinder before you start a long weld.
