Double Action Sealed Air Hand Pump, Manual

This double action pump inflates and deflates towables, kayaks, boats, airbeds, and other inflatables. It 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. This is a great option when your inflatable is almost full and there's back pressure. The accordion-style hose stretches to 4 ft. long and interlocks to the pump, so that it doesn't fall off while you're pumping.
