OVERVIEW

Precision Pressure Monitoring for Industrial Gases

The Western Enterprises WWWBG-25100-B is a premium replacement pressure gauge designed for the rigorous demands of industrial gas management. Featuring a 2.5-inch diameter face, this gauge offers enhanced visibility compared to standard 2-inch models, allowing technicians and operators to read pressure settings accurately from a greater distance. The scale is calibrated from 0 to 100 PSI, making it specifically suited for the "using" or delivery side of a regulator where precise low-pressure control is critical.

Engineered for Safety and Compatibility

Safety is paramount when handling high-pressure gases, particularly Oxygen. This gauge is manufactured and cleaned for Oxygen service, meaning it is free from oils and contaminants that could cause hazardous reactions. It is equally effective for use with Inert Gases such as Argon, Helium, Nitrogen, and CO2 mixtures commonly used in welding and industrial processes. The internal movement is constructed from high-quality brass, ensuring smooth operation and resistance to corrosion over time.

Robust Construction & Installation

Built to withstand the industrial environment, the gauge features a gold-painted steel case that protects the internal mechanism from minor impacts and abrasion. The lens is made from durable polycarbonate, reducing the risk of shattering. Installation is straightforward with a standard 1/4" NPT bottom mount connection, which is the typical thread size for medium-duty and heavy-duty regulators found in fabrication shops, laboratories, and manufacturing facilities. Whether you are refurbishing an older regulator or building a custom gas manifold, this gauge provides the reliability and accuracy required for professional applications.

FAQ

This gauge features a 1/4" NPT male bottom mount connection. This is a standard size for many medium and heavy-duty regulators, but please verify your regulator's port size before purchasing.

No. This gauge is marked for Oxygen or Inert Gas service. Acetylene gauges require specific internal materials and safety features tailored to Acetylene gas. Do not use this gauge on fuel gas regulators.

This is a 0-100 PSI gauge, which is designed for the 'Using' or 'Delivery' side (hose pressure). Tank pressure gauges typically read up to 3000 or 4000 PSI.

No, the gauge does not come pre-taped. You should use an oxygen-compatible PTFE tape or thread sealant when installing it to ensure a leak-free seal.

The case is made of gold-painted steel, providing better durability than plastic cases often found on cheaper alternatives.

It will fit any regulator that accepts a 1/4" NPT gauge thread. Many larger Victor, Harris, and Smith regulators use this size, but smaller 'compact' regulators often use 1/8" NPT. Check your existing gauge stem.

It means the gauge has been manufactured and packaged to be free of oils and greases. Oil can react violently with high-pressure oxygen, so this cleaning is a critical safety requirement.

While the pressure range is suitable, the internal materials are designed for dry gas. Using it with water may lead to corrosion or inaccuracy over time unless the gauge is specifically rated for hydraulic use.
