Duotone Kite & Wing Pump Adapter
The Duotone Pump Adapter with a built-in silicone sealing ring is specifically designed for use with Duotone kites and wings featuring the Airport II valve system.
This adapter is optimized for heavy-duty pump hoses from 2016 and newer, providing a secure, reliable fit. It can also be used with older pump hoses (pre-2016), although the connection may be tighter and may not lock in as firmly as with standard OEM adapters.
For older hoses, the adapter can still be used effectively—however, a quick modification (such as lightly filing down the small ridge nub) may help improve the fit and locking capability.
