Simply turn the release valve counter-clockwise and you''re pumping air only on the down-stroke; a great option when inflatable is almost full and there is back pressure
Accordion-style hose stretches to five ft. long and interlocks to the pump so it doesn''t fall off while you''re pumping
Very effective for -topping off- large towables in the boat, since peak pressure is an impressive 14 psi
This double-action pump inflates and deflates towables, kayaks, boats, airbeds and other inflatables
Delivers a continuous stream of air on both the up and the down strokes
Four universal valves are included to fit Boston valves and stem valves
