Presta valves can wear-down the seal on any pump head due to pressure and friction with the threads on the outside of the valve. Our Seal kit is installed in seconds using a 6mm Hex Driver. Steel threaded top cover that holds the seal is included to insure a fresh, tight connection. Instructions included.
