valve core

Valve core

The "valve core" is also called "airtight core." Mainly used for tire intake and to prevent tire leaks. The main body of the "valve core" is a small section of hollow upper end and a solid cylinder at the lower end. A small hole is opened in the lower side and communicates with the hollow part. The valve cores are mainly divided into: British valve needles, American valve cores, French valve cores, and German-style valve needles and Italian-style valve cores.

From the material can be divided into: zinc alloy and copper.

The valve core is an indispensable part of the tyre valve, so its quality is also a major factor directly affecting the sealability of the tyre valve.
