OVERVIEW

Reliable Replacement Gauge for Regulators and Air Lines

Keep your equipment running safely and accurately with this 2-1/2" Pressure Gauge. Whether you have a cracked lens on your flowmeter or a stuck needle on your air compressor regulator, this 0-100 PSI gauge is the perfect replacement part to get you back to work. The 0-100 PSI range is ideal for reading delivery pressure (the gas going to your torch or tool), giving you the precision you need to dial in the perfect flow.

Designed with a Lower Back Mount (LBM), this gauge screws directly into the back of most standard regulators and panel mounts, keeping the face easy to read while you adjust your settings. The plastic case is tough enough to handle the bumps and knocks of a busy shop environment without rusting or denting like cheap metal housings. The high-contrast dial ensures you can check your pressure at a glance, even from a distance.

Don't guess your settings—replace faulty gauges immediately to ensure consistent weld quality and tool performance. This gauge is compatible with inert gas regulators (Argon/CO2) as well as compressed air systems, making it a versatile addition to your spare parts bin.

  • Easy to Read: Large 2.5" face with clear numbers.
  • Standard Fit: Lower back mount fits common regulators.
  • Durable: Plastic housing resists shop wear and tear.

FAQ

This gauge measures pressure from 0 to 100 PSI.

The dial face has a diameter of 2.50 inches.

It features a Lower Back Mount (LBM), meaning the connection is on the back of the case, near the bottom center.

The case is made of plastic (PLA), offering corrosion resistance and a lightweight design.

Yes, if your regulator requires a 0-100 PSI gauge with a back mount connection (typically for reading the delivery pressure/flow), this is a suitable replacement.

BLU likely refers to the color of the gauge case or dial accents, which helps in identifying the gauge or matching it to specific equipment branding.

While many gauges are general purpose, gauges used for oxygen must be specifically cleaned for oxygen service to prevent combustion. Unless explicitly marked 'Use No Oil' or 'Oxygen Clean', assume it is for inert gas or air only.

Use a wrench on the brass connection stem (not the plastic case) to tighten the gauge into the port. Use teflon tape or thread sealant if appropriate for the gas service.
