OVERVIEW

Precision Replacement Gauge for Industrial Gas Regulators

The Western Enterprises BG-2-100 is a high-quality replacement pressure gauge designed for the rigorous demands of industrial welding and gas distribution systems. Engineered with a 2-inch diameter dial, this gauge provides clear and accurate readings for delivery pressures ranging from 0 to 100 PSI. It is specifically manufactured to meet the safety standards required for oxygen service, meaning it has been cleaned to remove all hydrocarbons and oils that could pose a combustion hazard in oxygen-enriched environments. Additionally, its material compatibility extends to inert gases, making it a versatile component for regulators handling Argon, Helium, Nitrogen, and CO2.

Constructed with a durable brass case (often gold or polished finish), this gauge is built to withstand the physical wear and tear typical of fabrication shops and manufacturing facilities. The internal mechanism is precision-calibrated to ensure reliable performance, critical for maintaining consistent flow rates and pressures in welding, cutting, and brazing applications. The gauge features a standard 1/4-inch NPT bottom mount connection, ensuring compatibility with a wide array of commercial and industrial gas regulators from major manufacturers. The lens is typically crafted from shatter-resistant polycarbonate or high-strength glass, protecting the dial face from impact and debris while maintaining visibility.

For maintenance and repair operations (MRO), having a reliable source of replacement gauges is essential to minimize downtime. A broken or sticking gauge can lead to inaccurate pressure settings, affecting weld quality or cutting performance. This unit serves as a direct replacement for damaged low-pressure (delivery) gauges on oxygen regulators and flowmeters. Its 0-100 PSI scale is particularly suited for applications requiring fine adjustment of outlet pressure, such as oxy-fuel cutting or MIG/TIG shielding gas delivery. Compliance with UL listing standards further assures the user of the product's safety and quality engineering.

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.
