The PKS North/Duotone Airport Pump Adapter/Nozzle with double silicone sealing ring is compatible with 2013 and newer North kites, and 2014 and newer Cabrinha kites with the Airlock 2 screw valve.
This adapter was built to fit newer model heavy duty pump hoses (2016 and newer.) The adapter does also fit older model pump hoses (prior to 2016) very tightly but does not lock in like standard OEM adapters. The adapter can be used as is or may need to be modified by filing down the tiny nub near the ridge of the adapter where it connects to the hose.
If you remove the Silicone sealing Rrings, this works perfectly in Core kites as well.
