What is the Difference Between American and French Valve Stems?

[LaDante]

American valve stems are larger and shorter, and you don't need to remove the cap when inflating. French valve stems are longer and smaller, and you must loosen the cap to inflate. Air guns can accommodate French valve stems, but for American valve stems, the pump must be detached before inflation. Below is an introduction to valve stems: 1. Function of valve stems: A small component used to inflate or deflate tires and maintain the seal after inflation. A standard valve stem consists of three main parts: the valve stem body, the valve core, and the valve cap. Next, we will provide a detailed introduction to automotive tire valve stems. 2. Types of valve stems: Bicycle valve stems, motorcycle and electric vehicle valve stems, car valve stems, truck and bus valve stems, agricultural and engineering vehicle valve stems, and special valve stems.
