Tire Tube Valve is used to inflate/deflate the inner tube of a tire. There are two main valve types available, Schrader and Presta.
The Presta valve (also called Sclaverand valve or French valve) is a valve commonly found in high pressure road style and some mountain bicycle inner tubes. It comprises an outer valve stem and an inner valve body. A lock nut to secure the stem at the wheel rim and a valve cap may also be present.
The Schrader valve (also called American valve) is a type of pneumatic tire valve used on virtually every motor vehicle in the world today.
