JACO FlowPro digital air pump with gauge is a powerful tool for all your needs. Designed for connection to an air compressor line, it quickly measures, inflates, and deflates tire pressure up to 200 PSI. It can also be used as a standalone gauge for pressure readings without a compressor. It offers ±1% full-scale accuracy with a resolution of 0.5 PSI. Featuring a solid steel body with durable powder coating and an 18-inch steel-braided air hose. The large 2.5-inch digital LCD display with backlight ensures easy readability, and the auto-off function saves battery life. A locking chuck with a self-sealing nozzle and quick-release valve prevents air leaks, ensuring a reliable seal. Built-in air bleed valve and trigger provide convenient control.
