OVERVIEW

Reliable High-Pressure Monitoring for Welding Regulators

Ensure your welding operations run safely and efficiently with this premium 1.5-inch High Pressure Gauge. Designed specifically for the demanding environment of industrial welding, this gauge is calibrated to read up to 4000 PSI, making it the perfect replacement for the "contents" side of your gas regulator. Whether you are monitoring Oxygen, Argon, or other inert gas cylinders, accurate pressure readings are critical for knowing exactly how much gas remains in your tank before starting a long job.

The gauge features a standard 1/8-inch NPT back mount connection, which is the industry standard for most compact and medium-duty welding regulators. Its 1.5-inch diameter face is compact enough to stay out of the way while providing clear, legible markings that allow operators to check cylinder pressure at a glance. A broken or stuck gauge can lead to unexpected downtime or unsafe operating conditions; replacing it is a quick and cost-effective maintenance step that restores full functionality to your equipment.

Constructed with durability in mind, this gauge withstands the vibrations and minor impacts common in workshops and job sites. It is an essential spare part for any welder's toolkit, ensuring that a cracked lens or bent needle doesn't halt production. Compatible with a wide range of regulator brands, this high-pressure gauge offers peace of mind and precision performance.

Key Benefits

  • Accurate Monitoring: clearly displays cylinder pressure up to 4000 PSI.
  • Universal Fit: 1/8" NPT threads fit the majority of standard welding regulators.
  • Compact Design: 1.5" size is unobtrusive yet easy to read.

FAQ

This gauge has a 1/8-inch NPT (National Pipe Taper) thread, which is the standard size for most welding regulator gauge ports.

This is a high-pressure gauge (4000 PSI), designed to measure the tank (cylinder) pressure, not the working line pressure.

No, this gauge reads up to 4000 PSI. Acetylene gauges typically require a much lower scale (usually up to 400 PSI for contents) and have specific internal construction for safety with acetylene gas.

Unscrew the old gauge using a wrench. Apply a small amount of appropriate thread sealant (ensure it is oxygen-safe if using on oxygen) to the new gauge threads, and screw it into the port, tightening firmly with a wrench.

This is a back-mount gauge, meaning the threaded connection comes out of the center of the back of the gauge case.

It will fit most regulators that accept a 1/8" NPT thread and have a 1.5" gauge housing clearance. It is a very common standard size.

It is compatible with non-corrosive gases typically used in welding, such as Oxygen, Argon, CO2, Helium, and Nitrogen, provided the pressure range is appropriate.
