The K-Pump K40 High Pressure Hand Pump is the smaller version of the K-400, much more compact and easy to stow where space is limited. Featuring the same two-stage design, and both high-volume and high-pressure modes, the K-40 is only 24″ in length and 4″ in diameter. Weighing in at only 3 lbs, it stows nicely on your boat or board thanks to the stow-friendly carrying bag.

• 24″ in length, 4″ in diameter and 3 lbs in weight.
• The primary stage delivers approx. 1.2 gallons of air per stroke, filling your tubes quickly.
• When the pressure in the chamber increases and pumping starts to become difficult, a simple twist of the handle locks out the high-volume primary stage and locks in the high-pressure “top-off” stage.
• Nozzle end and included adapters fit most inflatable boat valves – Leafield, Halkey-Roberts, Summit, Boston, AD-2 and military valves.
• Ergonomic design is comfortable to use, even with extended use.
• Efficiently operated by one person. No hoses to kink and pull out.
• Easily stowed, takes up little space.
• Rugged construction is backed by an unlimited 2-year warranty.
• All K-Pumps float!
• A spare O-ring for each of the stages is included with the pump.
