Copper core (recommended purchase)

Made of pure copper material, the inner core pure copper has a strong pressure resistance, guarantees the use of medium pressure resistance, is not easy to damage, safe and airtight.
Plastic core
The plastic core is made of plastic material, so if the inner core color is black, it is a plastic core.

Tri-color warning - different tire pressures show different colors

* Under the standard tire pressure, the transparent window should be green, the vehicle is running normally (about 2.3Bar), so green represents safety (normal tire pressure).
*The tire pressure is lower than the standard by about 10%, the transparent window should be yellow, and the air is timely (2.0-2.3bar), so yellow represents the warning (the tire pressure is low).
*The tire pressure is lower than the standard by about 25%, and the transparent window is red.
That is, qi (less than 2.0 bar), so red represents danger (tire pressure is too low).
