22322 - Acetylene Cylinder Pressure Gauge 0-400 PSI 2-Inch Dial

Technical Overview: ESAB 22322 Acetylene Gauge

The ESAB 22322 is a precision-engineered replacement pressure gauge designed specifically for oxy-fuel welding and cutting applications. This unit is calibrated for a pressure range of 0 to 400 PSI (pounds per square inch), making it the standard specification for monitoring cylinder contents on the high-pressure side of an acetylene regulator. The gauge features a 2.00-inch diameter dial face, providing a balance between compact footprint and readability. The scale is clearly marked, allowing operators to quickly assess remaining tank pressure and ensure safe operation parameters are maintained.

Constructed with a robust ABS (Acrylonitrile Butadiene Styrene) plastic case, this gauge offers significant advantages in industrial environments. The ABS housing provides excellent resistance to impact, chemical exposure, and corrosion, which is particularly beneficial in shop environments where equipment is subject to rough handling and atmospheric contaminants. Unlike metal cases that may dent or rust, the ABS shell maintains its structural integrity and aesthetic appearance over time. The internal mechanism is designed to provide consistent accuracy, ensuring that gas flow calculations and safety checks are based on reliable data.

The connection interface is a standard 1/8-inch NPT (National Pipe Taper) male thread, the industry-standard size for the majority of welding gas regulators. This ensures broad compatibility not only with ESAB equipment but also with regulators from other major manufacturers requiring a bottom-mount gauge of this specification. The unit is color-coded red, adhering to international safety standards for fuel gases, thereby preventing cross-connection hazards and facilitating immediate visual identification of the gas service line. This gauge is an essential component for maintaining the safety and efficiency of oxy-acetylene setups.
