Air pressure gauge (also called a tire pressure gauge inflator).
It’s used to check and control air pressure in things like:
• Car tires
• Motorcycle tires
• Truck tires
• Air compressor lines
What it does
• The round dial shows the pressure in PSI and bar
• You connect it to a tire valve or compressor hose
• It tells you if the tire is under-inflated or over-inflated
