North and Duotone Airport Valve

The OEM Duotone AIRPORT valve Mounted in an AIRTIME 4" 'peel-n-stick' base.
This blurb plagiarized straight from the original website: The valve is suitable for both, inflation and deflation. The deflation option is integrated, which means no external deflation pin is required. Deflation is simply activated by turning the blue wheel on the inside of the valve completely to the right.
