Sullair 405764 Pressure Gauge 0-25 PSI 1/8 NPT 2-3/4 Dia

The Sullair 405764 pressure gauge provides a 0–25 PSI range with a 1/8 NPT connection and a 2-3/4 inch dial diameter. Designed for use on Sullair equipment and other pneumatic systems that accept 1/8 NPT gauges, it allows quick verification of system pressure at a glance, making it easier to diagnose low-pressure concerns or verify regulator outputs. The 2-3/4 inch dial diameter ensures legible readings within typical control panels and instrument housings, helping technicians confirm pressure without excessive panel removal. With a 0–25 PSI range, it is well suited for monitoring low-pressure sections of compressed-air lines, regulator outlets, and ancillary pneumatic circuits where nearby readings support accurate adjustments. The gauge bears the Sullair brand and the part number 405764, confirming the exact specification for replacement in compatible installations. Its 1/8 NPT connection matches common ports on air compressors, manifolds, and test points, enabling straightforward integration into existing systems.
