21867 - ESAB 2-Inch Replacement Regulator Gauge 0-400 PSI

Precision Monitoring for Industrial Gas Regulation

The ESAB 21867 Gauge is a high-quality replacement component designed to restore the functionality and safety of your gas regulation equipment. In the realm of industrial welding and cutting, accurate pressure monitoring is not merely a convenience—it is a critical safety requirement. This gauge is engineered to provide precise readings for delivery pressure, ensuring that downstream equipment receives the exact flow required for optimal performance.

Featuring a 0-400 PSI range, this gauge is typically utilized on the low-pressure (delivery) side of regulators used for inert gases, oxygen, or compressed air. The 400 PSI scale offers sufficient headroom for most welding applications while maintaining enough resolution to allow operators to dial in specific settings accurately. The internal mechanism is built to withstand the vibrations and minor shocks common in industrial environments, ensuring consistent calibration over the unit's service life.

The physical construction centers around a standard 2.00-inch diameter case, a universal size that fits the gauge guards and housings of most major regulator brands. The connection is a standard 1/8-inch NPT thread, machined to tight tolerances to ensure a leak-free seal when installed with appropriate thread sealant. The face of the gauge is finished in a bright white with bold, high-contrast black numerals and graduation marks. This design consideration is vital for low-light shop environments, allowing operators to verify pressure status quickly and without ambiguity.

Whether you are maintaining a fleet of regulators in a large fabrication facility or repairing a single unit, the ESAB 21867 offers the reliability expected from a top-tier welding manufacturer. It serves as a direct replacement for damaged, fogged, or stuck gauges, helping you maintain compliance with safety standards and ensuring your gas delivery systems operate within their specified parameters.
