valve stem

A **valve stem** is a critical component in various mechanical and automotive systems, serving as the part of a valve that provides a passage for air or fluid to enter or exit. In automotive applications, valve stems are commonly found on tires, allowing for inflation and deflation while maintaining an airtight seal. They play an essential role in maintaining proper pressure, ensuring safety and performance. Valve stems come in different materials and designs depending on their specific use, ranging from rubber-based stems for tires to metal stems in engine valve assemblies.
