The 9mm valve is a very common inflate valve used for many years on many kites as the main inflate valve as well as on kites where you pump the struts up separately from the leading edge. This one way valve lets air enter while pumping but stops air from going out. Simply squeeze the valve to let air out when deflating or the one-way flap can be cut out to create a 2-way valve.

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 "Valve Patch Size" option is to select the size of the Tear-Aid patch the valve is attached to. Standard valves have a 3-inch diameter and the Mega patches have a 4-inch. This extra inch on the Mega means 77% more adhesive base and surface area compared to the standard valve patch size. The Mega patch is necessary when the old valve is cut from the bladder or the bladder is torn or warped when the old valve is removed. The additional surface area provided by the Mega valve patch allows quick and easy bladder repair, eliminating the need for an additional bladder.
