AstroAI Tire Pressure Gauge with Inflator 100 PSI 2.5" Glow Dial
Combines a 2.5" glow dial gauge, inflator and deflator in one tool calibrated to ANSI B40.1 accuracy up to 100 PSI
- Accurate readings within +/-1 PSI across 0-100 PSI range
- 3-in-1 tool inflates, deflates and checks pressure
- Large 2.5" glow dial for clear visibility in low light
- Heavy-duty stainless steel and brass construction for durability
- Compatible with Schrader valves and 1/4" NPT air compressors
Precision calibration for daily driving
The AstroAI Tire Pressure Gauge with Inflator is a 3-in-1 tool that measures, inflates and deflates tyres through a single Schrader-valve connection. Its 2.5 inch glow dial reads 0 to 100 PSI with a resolution of plus or minus 1 PSI, calibrated to ANSI B40.1 accuracy. Heavy-duty stainless steel and brass construction withstands frequent shop or roadside use. Drivers who want one device for pressure checks and top-ups without switching fittings will find it practical.
Replaces separate gauge and chuck setups
Owners currently juggling a standalone pencil gauge and a clip-on air chuck can consolidate both into this trigger-operated unit. Press the trigger to inflate, release to stop, and press the reset button to bleed excess pressure while the chuck remains seated. The jump is worth it when you regularly adjust pressures on multiple vehicles or need to deflate quickly for off-road traction, eliminating the back-and-forth between two tools.
Fits standard 1/4 inch NPT compressor lines
The quick-connect coupler threads onto any 1/4 inch NPT air compressor hose, so the gauge becomes a permanent inline accessory. No proprietary fittings or adapters are required, freeing the operator from hunting for matching couplers. The rubber hose provides enough reach to access all four wheels on most passenger vehicles without moving the compressor. Builders needing dual-head chucks for inner dual wheels or a digital readout for fractional PSI will need a different instrument.

Questions about this item
Does the 2.5" glow dial gauge need any special fittings to connect to a standard Schrader valve?
The heavy-duty air chuck and quick-connect coupler are designed for direct attachment to Schrader valves without additional adapters.
What is the correct sequence for using the trigger and reset button during inflation?
Connect the chuck, press the trigger to inflate to the desired pressure, release the trigger to stop, then press the reset button to bleed excess air if needed.
Which parts of the inflator gauge are most likely to wear out and require replacement?
The rubber hose, brass quick-connect coupler, and stainless steel chuck are the primary wear items; the ANSI B40.1 calibrated dial mechanism does not require user recalibration.
