WWWBG-154000 - 1.5-Inch High Pressure Regulator Gauge 4000 PSI Oxygen/Inert

Precision High-Pressure Monitoring for Industrial Gas Regulators

The WWWBG-154000 Pressure Gauge is a critical component for the safe and efficient operation of industrial gas delivery systems. Designed specifically for the high-pressure side of welding regulators, this gauge provides a clear and accurate reading of cylinder contents up to 4000 PSI. Maintaining awareness of remaining gas pressure is essential for process continuity, preventing unexpected downtime during critical fabrication or analytical tasks.

Engineered with a 1.5-inch diameter dial, this gauge is optimized for compact regulators and flowmeters where larger gauges might be obtrusive or prone to damage. Despite its small footprint, the scale is legible and precise. The connection is a standard 1/8" NPT bottom mount, widely used across the industry for regulator bodies manufactured by major brands. This universality makes it an excellent stock item for maintenance, repair, and operations (MRO) inventories.

Safety is paramount when handling compressed gases, particularly oxidizers. This gauge is manufactured and cleaned for oxygen service, ensuring it is free from oils and contaminants that could react violently under high pressure. It is equally suitable for inert gases such as Argon, Helium, Nitrogen, and CO2/Argon blends used in MIG and TIG welding. Whether you are refurbishing older equipment or replacing a damaged unit, this gauge delivers the reliability required for professional gas control.

Technical Reliability

Constructed with durable materials to withstand the rigors of shop environments, the internal mechanism is designed to resist vibration and shock common in industrial settings. The brass connection ensures a leak-tight seal when properly installed with compatible thread sealants (approved for the specific gas service). This gauge serves as a primary indicator for cylinder change-outs, helping facility managers optimize gas usage and logistics.
