TheCushcore Tubeless Air Valvesare 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 tire sealant. A locknut with o-ring seal and valve cap are included
