CUSHCORE VALVE SETKEEPING YOU INFLATEDCush Core tubeless air valves are specially designed to work with a Cush Core insert. The air passageway is T-shaped, rather than a simple through-hole, which prevents the insert from obstructing airflow through the valve. The valve body is CNC machined from 6061 T-6 aluminum, anodized black, with a tapered rubber collar permanently bonded at the sealing interface. The valve core can be removed to add tire sealant. A locknut with an o-ring seal and valve cap are included.
