The 7mm and 9mm Pump Adapter is compatible with almost all kites prior to about 2008. Nearly all older kites which include the 2 valve inflate and deflate systems included 9mm or 7mm valves. This is also the adapter used for inflating struts on kites without a one-pump system.
*NOTE* - This adapter set was built to fit newer model heavy duty pump hoses (2016 and newer.) The adapter does also fit older model pump hoses (prior to 2016) very tightly but does not lock in like standard OEM adapters. The adapter can be used as is or modified by filing down the tiny nub near the ridge of the adapter allowing it to lock in to the pump hose like OEM adapters.
*This is the same adapter that comes with the PKS Pro Flow Kite Pump
