This new design allows more than 50% more air than our earlier model. New and improved Inflation valve adapter with torque tabs allows an easy connection from a high pressure air supply to your inflatable SUP, inflatable kayak or RIB. The schreader valve or car/bike tire inflation valve connects easily to a compressor or other electric pump commonly used for fast inflation. The hook locks make a positive lock on the board, kayak or rib valve. The part fits Halkey Roberts H3 valves and Bravo as well as a wide range of valves on iSUP like Wakooda boards and others. We include an extra washer so you can adjust the fit to make an air tight connection. Switch the part washer with your board/kayak/boat valve cap washer for an air tight fit. The larger the inflation pump you use, the faster the inflation. The difference in air flow is especially noticeable when using a smaller 12 volt electric pump.
