OEM valve used on Core kites. This is the inflate valve used on both the struts and the leading edge bladder. Hoses connect to these valves so that air can flow from the l.e. bladder to the struts.This valve comes on a 4" round adhesive base. The adhesive base has "body" so you're not fighting with thin floppy Tear-Aid when trying to attach it to a bladder. Can be used to replace failed or damaged valves.
