The FlowPro Tire Inflator Gauge is a shop-grade inflator that connects to an existing air compressor line to inflate and deflate tires with a dial gauge reading up to 100 PSI. Its standout part is the factory-installed Lightning S-Series chuck, whose AirLock internal locking system grabs and holds the valve stem with a push and releases without air loss. It suits garage and shop users who already own a compressor and want fast, repeatable pressure work. Against typical clip-on or dual-foot chucks, the locking chuck is the differentiator; owners rate it highly, though it is useless without a compressor and the gauge tops out at 100 PSI.

Owners rate it 4.9 out of 5 across about 1,000 ratings, with most praise going to the locking chuck and leak-free seal. Complaints are few and center on the compressor requirement and the 100 PSI limit.
The FlowPro Tire Inflator with Pressure Gauge connects to an air compressor line to inflate and deflate tires. It has a 2-inch analog dial that glows in the dark, so it can be read in a dim shop, a garage or at night. It measures from 5 to 100 PSI and needs no batteries.
The Lightning S-Series Air Chuck is factory installed on the end of the 21-inch rubberized hose. It locks onto the tire valve stem with a push and stays locked under high pressure or movement. A quick-release feature disconnects the chuck from the valve stem without air loss. The chuck is compatible with other Lightning Series air chucks, which are sold separately.
A built-in bleeder valve lets air out of overinflated tires and resets the dial reading to zero. The unit attaches to standard 1/4-inch NPT inflation tools. It can also be used on its own as a tire pressure gauge, without a compressor connection.
