AstroAI ASITIG250B Digital Tire Inflator Gauge, 250 PSI, Backlit LCD, ¼-inch NPT

For drivers who need a practical way to check and adjust tyre pressure, the AstroAI ASITIG250B combines a digital gauge with an inflator and deflator in one tool. It is designed for use with a compatible ¼-inch NPT air compressor connection.

The backlit LCD displays pressure in PSI, kPa, bar or kg/cm², so you can use the unit that suits your routine. A 22-inch stainless braided hose and rotatable dial make it easier to position the gauge at the valve while working.

Use the trigger to inflate or release air, then read the pressure on the display as you make adjustments. That combination is useful for regular vehicle checks and for topping up other compatible inflatables.

The gauge is designed to check pressure while you inflate, rather than requiring a separate pressure checker and inflator for the task. Its trigger supports one-handed operation: squeeze lightly to deflate and fully to inflate. The LCD backlight helps keep the reading visible in dim conditions, while the auto-on function responds when pressurized air is detected and the unit switches off after 15 seconds of inactivity. An integrated flashlight adds a handy light for emergency use.

What it works with

The ¼-inch NPT connector is specified for compatible air compressors. The gauge is intended for cars, SUVs, trucks, motorcycles, bicycles and RVs, as well as balls, air pillows, cushions and mattresses. For tire maintenance, connect it to the matching compressor outlet, secure the chuck on the valve stem and use the display to guide inflation or deflation. The brass chuck is made to lock onto the valve and help stop leaks during use, the braided hose offers flexibility while you position the tool.

Who it’s for

This inflator gauge suits drivers who want pressure readings and adjustment controls together, whether they are checking a car before a trip, maintaining an SUV or truck, or looking after bicycle and motorcycle tires. It is also useful around the garage for air-filled items such as balls and mattresses. The multiple pressure units make it easier to work in the format you already use, while the clear digital display and single-hand trigger keep the task straightforward.

Is it worth it?

The main benefit is having a pressure gauge and inflation controls in the same tool. The 250 PSI range, four selectable units, backlit screen and flexible stainless braided hose support routine checks across a range of vehicles and other inflatables. Choose it when you want a compressor-connected gauge that can both add and release air, with the pressure reading available as you work. Its specified ¼-inch NPT connection makes matching the compressor outlet the practical first step, once connected, the integrated controls make it a useful addition to a home garage or vehicle-maintenance kit.
