This heavy-duty foot pump is the perfect tool for inflating and deflating towables, boats, and other inflatables. The pump features a 46-inch-long hose and 5 adapters, including Boston and stem, to fit most valves. It reaches a maximum air pressure of 2.9 psi, allowing for quick and secure inflation of large towables. Compact size allows it to fit under kayak decks or boat seats, great for "topping off" your towables.
