Airhead Double Action Hand Air PumpPerfect For Topping off Towables - This pump delivers a continuous stream of air on both the up and down strokes. It quickly inflates and deflates tubes, airbeds, boats, toys and other inflatables. Four universal valve fittings are included. The accordion-style hose stretches to 5 ft. long and interlocks to the pump, so that it doesn't fall off while you're pumping. Capacity is approximately 68 gallons / 60 strokes. Especially great for topping off towables, since peak pressure is 14 psi.California Residents:WARNINGCancer and Reproductive Harm -P65Warnings.ca.gov
