This adapter collar securely holds 9mm valves in place.

Some original valves may have a small ridge to prevent the valve from falling back inside the sleeve of the kite when the bladder is not inflated. This collar slides on over the 9mm valve after the bladder is installed and hold the valve in place.

This collar should be used with U-STICK 9mm valves when going in Flexifoil kites. The collar is also useful in older kites where the hole in the fabric is worn and the valve wants to fall back in.
