21865 - ESAB 2-Inch Replacement Pressure Gauge 0-30 PSI 1/8 NPT ABS Case

Precision Low-Pressure Monitoring

The ESAB 21865 is a specialized pressure gauge designed for industrial and welding applications requiring accurate monitoring within the 0-30 PSI range. Engineered with a 2.00-inch diameter dial, this gauge provides a clear and concise readout, essential for maintaining optimal system parameters. The unit features a standard 1/8-inch NPT connection, making it a versatile replacement part for a wide variety of regulators, flowmeters, and pneumatic control systems commonly found in manufacturing and fabrication environments.

Durable Construction

Unlike traditional metal-cased gauges that may be susceptible to denting or corrosion in harsh environments, this model utilizes a robust ABS (Acrylonitrile Butadiene Styrene) plastic case. This material choice offers superior impact resistance and longevity, ensuring the internal mechanism remains protected during daily operations. The lightweight nature of the ABS housing also reduces the mechanical load on the connection point, which is particularly beneficial when mounted on delicate regulator bodies or lightweight piping systems.

Clear Visibility

Readability is paramount in safety-critical applications. This gauge features a bright white face with distinct, high-contrast markings that allow operators to verify pressure levels at a glance. Whether used for monitoring shielding gas line pressure, checking low-pressure pneumatic tools, or as a replacement component on welding outfits, the ESAB 21865 delivers reliable performance. Its specific 0-30 PSI range is ideal for applications where fine resolution at lower pressures is required, preventing the reading errors common when using high-range gauges for low-pressure tasks.
