What is the function of a tire pressure cap?

The function of a tire pressure cap: It assists in measuring the air pressure of car tires. The user secures this indicator onto the tire valve stem and visually observes the color changes inside the transparent cap to determine whether the tire pressure is sufficient, thereby taking further action. The tire pressure cap is commonly known as a valve-type tire pressure cap, air pressure cap, tire warning cap, or tire pressure monitor. The working principle of the tire pressure cap relies on the cap pressing into the valve pin to obtain the tire pressure, which then pushes the display window. At this point, the sealing function of the valve pin is no longer effective. If the cap leaks, the tire will also lose air. However, the sealing and quality reliability of the tire pressure monitoring cap are far inferior to the valve stem itself, especially during high-speed driving, making it less secure.
