The Airhead Double Action Hand Pump efficiently inflates and deflates a variety of inflatables, including towables, kayaks, boats, and airbeds. With a 2-liter volume per stroke and a peak pressure of 14 psi, it delivers continuous airflow on both up and down strokes for faster inflation. The release valve allows switching to single-stroke pumping when needed. Equipped with four universal valve fittings compatible with Boston and stem valves, plus an accordion-style hose that extends to 5 feet and securely locks to the pump, it ensures reliable, hands-free operation during use.
