Airhead Hand Air Pump

This double-action pump inflates and deflates towables, kayaks, boats, airbeds and other inflatables.Delivers a continuous stream of air on both the up- and the down-strokes.Simply turn the release valve counterclockwise and youre pumping air only on the down-stroke; a great option when inflatable is almost full and there is back pressure.Four universal valves are included to fit Boston valves and stem valves.Accordion-style hose stretches to five ft. long and interlocks to the pump so it doesnt fall off while youre pumping.Volume is two liters/stroke.Very effective for topping off large towables in the boat, since peak pressure is an impressive 14 psi
