PKS Boston Valve Pump Nozzle 

The Boston valve pump adapter/nozzle fits on most standard kite pump hoses. 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 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.
