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 this 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. There is an integrated pressure gauge that will begin to register once you reach 10 PSI. For all PEAK and ISLE Paddle Boards we recommend inflating your SUP to the suggested 15 PSI.
