Best V3 or North One pump valve. This valve is used on the struts and leading edge and used for the one pump system. Valve is about 35mm tall and fits into a hole of about 22mm. Use Dr Tuba Best/North one pump clips to secure the air pipe in place or re use the existing ones.
This is the valve only. We use these in our repair centre to repair kite bladders, they don't come pre-prepared so only suit experienced repairs and other repair centres. We have made an instructional video showing a technique we developed over many years to fit these here-
