I have a Best Waroo kite bought used and never used it myself. It is missing the plug for the deflation valve. The opening is about 15mm in diameter. Does anyone have any idea where I might find a replacement?? I don't really want to have to replace the entire, perfectly good, bladder ...
I have no idea what the particular plug on your kite looks like, but most kite repair places, such as airtime, or fixmykite, should have these. My local kite store carries replacement valves with plugs, including the Cab style threaded plug.
