The Ozone Big Boston screw valve will replace the inflate/deflate valve on 2011 and newer Ozone Kites. This valve is also a compatible replacement for the Liquid Force Max Flow Valves (kites 2011 and newer) and Switch kites (2015 and newer).
From the leaders in kite repair technology, Fixmykite.com's Self-Stick Valves will stick on all bladders. Simply peel and stick to make a fast and easy repair on an old bladder or attach to a brand new bladder. The specially formulated adhesive is incredibly durable making for a permanent repair. Everything needed for installing the new valve is included in the package: alcohol wipe and detailed instructions.
The "Add Velcro" option provides you with velcro attached at the base of the valve as you would see on an original factory bladder. The velcro on the valve adheres to the velcro on the inside of the leading edge casing, stopping the bladder from twisting when tightening or loosening the screw cap which prevents a blow-out from a twisted bladder.
The "Bladder Patch Install Kit" option is for when your old screw valve has to be cut out of the bladder leaving a hole in the bladder larger than the patch size of the screw valve. The Bladder Patch Install Kit includes a 6x6-inch (15.24 x 15.24cm) adhesive patch and 5x6-inch bladder protection sheet. Use the bladder protection sheet and large patch to patch the large hole cut in the bladder, and then install the screw valve on top of the patch. If your old valve peels off of the bladder easily, you do NOT need the bladder patch install kit.
