One pump valve to fit RRD kites. This valve is quite tall with 90 degree bend and used on the struts and leading edge for the one pump system. Valve is about 27 mm tall and fits into a hole on the strut/edge of about 17mm.
These are no longer available, please use the V2 ones here as they are a direct replacement-
