OVERVIEW

Get Accurate Readings with a Tough Replacement Gauge

If you can't read your regulator, you can't set your flame or shield gas correctly. A cracked face, a bent needle, or a gauge that just won't zero out is more than an annoyance—it's a quality control issue waiting to happen. This 2-inch replacement pressure gauge from Western Enterprises is the standard fix for the "delivery" or "working pressure" side of your oxygen or inert gas regulator. With a range of 0-100 PSI, it gives you the resolution you need to dial in the perfect pressure for your cutting torch or welding machine.

Safety is the number one priority when dealing with compressed gases, especially oxygen. This gauge comes factory-cleaned for oxygen service, meaning it's free of oil and grease that could cause a dangerous reaction. It is also perfectly safe and compatible for use with inert shielding gases like Argon, Helium, and CO2 mixes. The solid brass case is designed to take the bumps and knocks of a busy shop or the back of a welding rig truck. It screws right into any standard regulator port that accepts a 1/4-inch NPT thread, making it a universal solution for many different brands of equipment.

Don't guess at your settings. Whether you are replacing a gauge on an old Smith, Victor, or Harris regulator (check your thread size first, as some small regulators use 1/8"), this 1/4" NPT gauge is the industry standard for full-size equipment. The clear markings on the white face make it easy to check your pressure at a glance from across the bench. Keeping a spare gauge in your toolbox is a smart move for any serious fabricator or mobile welder. Swap out that broken gauge today and get back to welding with confidence, knowing exactly what your equipment is delivering.

Key Features for Welders

  • Easy to Read: Crisp 0-100 PSI markings on a 2" face.
  • Safe: Cleaned for Oxygen service; works with Argon/CO2 too.
  • Durable: Brass housing resists corrosion and shop abuse.
  • Universal Fit: Standard 1/4" NPT thread fits most medium-to-heavy duty regulators.

FAQ

This gauge typically features a 1/4" NPT male bottom mount connection, which is standard for most medium and heavy-duty regulators. Always verify your regulator's port size before ordering.

No. This gauge is rated for 100 PSI, but acetylene gauges usually have a red line warning above 15 PSI and specific internal construction. While it fits physically, it is labeled and intended for Oxygen or Inert gases. Always use a gauge specifically marked for Acetylene fuel gas for safety.

No, this is a low-pressure gauge with a maximum range of 100 PSI. Cylinder pressure gauges typically read up to 3000 or 4000 PSI. Connecting this gauge to high cylinder pressure will destroy the gauge and could cause injury.

You should use an oxygen-safe PTFE tape or thread sealant. Do not use standard white plumber's tape if it is not rated for oxygen service. Apply tape starting one or two threads back to prevent tape shreds from entering the regulator.

It means the gauge has been manufactured and packaged in a way that ensures no oils, greases, or hydrocarbons are present inside the wetted parts. This is critical because oil can spontaneously combust in the presence of high-pressure oxygen.

Most full-size Victor regulators use 1/4" NPT gauges, so yes, it likely will. However, some smaller 'portable' or 'tote' style regulators use smaller 1/8" NPT gauges. Check the diameter of the threaded stem on your old gauge to be sure.

While physically capable of measuring water pressure up to 100 PSI, this gauge is designed for gas service. Using it with water may corrode the internals if they are not designed for liquid service, and once used with water or oil, it can NEVER be used for oxygen again.
