CushCore tubeless air valves are specially designed to work with a CushCore insert. The air passageway is T-shaped, rather than a simple through-hole, which prevents the insert from obstructing air flow 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 tyre sealant. A locknut with o-ring seal and valve cap are included. CushCore tubeless air valves are specially designed to work with a CushCore insert.
