This big Boston valve (screw valve) pump adapter / nozzle fits on any standard kite pump hose. It works with several large Boston valves (screw valves) on the market today including Ozone (2011 and newer), and Naish, Crazyfly, and Airush (2015 and newer,) and Switch kites.
*NOTE* - *This adapter was built to fit newer model pumps (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 modified by filing down the tiny nub near the ridge of the adapter allowing it to lock in to the pump hose like OEM adapters.
**This adapter is very similar to, but not the same as the Cabrinha adapter, Best 2008 adapter, or North 2014 and newer adapter. It will probably not work on these three kite brands.**
*This is the same adapter that comes with the PKS Pro Flow Kite Pump
