Duotone Pump Multi-Purpose (3-19 PSI)

This threaded 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. This adapter screws onto the top of the Boston valve for a more secure fit compared to the friction-fit adapters typically found on most pumps.

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.

Please note, this 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 with these three kite brands.
