This high-pressure hand pump was designed to inflate your stand up paddle boards. The pump’s hose has a turn-to-lock insertion that easily secures the pump to your SUP. This pump is dual-action, meaning that it pumps air on both the push down and pull up for faster inflating. It features an integrated pressure gauge that will begin to register once you reach 10 PSI. We recommend inflating all PEAK inflatable paddle boards to the suggested 15 PSI.
