Tubeless valves are generally made from rubber with a central core of metal containing the components required for inflating/deflating the tyre and providing air seal. The valve core provides the primary air seal in a tubeless valve, a secondary seal is provided by the valve cap that also acts as a seal to prevent the ingress of dust and moisture into the valve itself.
