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).
*NOTE* - It 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.
