From the five-year experience gained with HP2, we projected HP8 which is the most powerful single-barrel/double-action pump of GRI family. The bigger capacity, the very high efficiency and the ergonomics of this pump make it possible to inflate big RACE boards in a short time & less effort.
-max pressure 26psi
-handle super ergonomic
-rotating switch for double/single action
-rotating pump adapter to make it easier to connect the hose
-seal sand antis and filter for long life of pump and SUP board
-high-airflow piston for an easier inflation
-shockproof gauge meter
