Single Action Hand Pump, High Pressure. Not, Double Action Air Pump, Sup, Kite.

Single action high volume high pressure air pump. Suitable for high pressure air products such as kite surfing kites, surf boats, inflatable stand up paddle boards. Intake stroke has almost no friction. Please see my video demonstration at the link below. While blocking the air outlet the pump pressure chamber supports my body weight of 73 kgs with very minimal air loss from the high quality rubber o ring inside.

However many standard kite pumps have poor pressure. This one is excellent. Thanks for looking
