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. Features: High-quality 6061 T6 Aluminium tubeless valves. Drilled base to improve sealant flow around insert. Tapered nitrile rubber seal. Unique cross drilled base for air flow around inserts. Removable valve core for faster flow of air and sealant. Specification: Valve core tool included. Weight: 0.2 lbs. Lengths: 44mm or 55mm.
