The FlowPro Digital Series by JACO is a professional inline tire inflator gauge that connects to a shop air compressor line. It reads up to 200 PSI and is rated to ASME B40.7 Grade 1A accuracy, the class used for precision industrial gauges. Its standout part is the factory-installed Lightning S-Series chuck: a push-to-lock connection with a quick release that vents no air. That makes it a strong pick for technicians and serious home mechanics who inflate tires all day. Against cheaper clip-on inflators, it trades a basic build for a corrosion-resistant zinc-alloy chuck and a digital readout, and owners rate it highly for accuracy and easy valve engagement.

The FlowPro Digital Series Tire Inflator Gauge connects to an existing air compressor line for tire pressure maintenance in a garage or shop.
It comes with the Lightning S-Series Air Chuck factory installed. The chuck uses a push-to-lock quick-connect connection and a quick-release that lets go with no air loss. It is made of corrosion-resistant zinc alloy.
The inflator is also compatible with the Lightning Lock-on Air Chuck collection, which is sold separately as add-on attachments.
