There is nothing worse than getting to beach only to find out you lost your adapter and after running about finding out your local kite stores don't have one in stock...so I present a solution to you maker/kiters: this is the adapter to connect your pump to an older Cabrinha kite inflate valve. I think this will work on 2012 and earlier kites (I know it fits a 2010 Convert). It took about an hour for my printer running quite slow to keep the detail up and stringing down. It took me that long to drive to the store to find out they didn't have what I needed. I've credited the knurl library I used (and included) on this thing, but the thread library came from here: http://dkprojects.net/openscad-threads/ All I've measured out was the actual pump end (which anyone can borrow if they need to make an adapter to fit this type of air hose), and the threads for the Cabrinha Airlock valve. Print water tight--100% infill and you might want to slow it down a little and keep the heat low for the details and to keep the threads from sagging. I used 0.1 layer height, 17 perimeter speed, with no brim or additional support at 185*. You can disable the small supports for the nipples. Mine broke away clean and it fit straight off the bed after snapping the supports. The Cabrinha thread for this is 18mm x 1.5 for anyone interested.
