The Airhead Double Action Hand Pump is perfect for topping off towables and other inflatables for the perfect fill. This is the perfect tube pump for boats because it delivers a continuous stream of air on both the up and down strokes for more efficient filling. The pump quickly inflates and deflates tubes, airbeds, boats, toys, and other inflatables with ease. Four universal valve fittings are included with the Double Action Pump, which features a five-foot accordion style hose. This hose interlocks to the pump, so that it doesn’t fall off while you’re pumping.
