Double action pump inflates and deflates towables, kayaks, boats, airbeds, and other inflatables

Delivers a continuous stream of air on both the up and down strokes

Simply turn the release valve counter-clockwise and you're pumping air only on the down-stroke

Great option when your inflatable is almost full and there is back pressure

Four universal valve fittings are included to fit Boston valves and stem valves

Accordion-style hose stretches to 5 ft. long and interlocks to the pump, so that it doesn't fall off while you are pumping

Volume is 2 liters / stroke

Very effective for topping off large towables in the boat, since peak pressure is an impressive 14 psi
