Pumps

This replacement high volume O-ring is used on the two-stage K-Pumps. This is the large O-ring that is used on the K-Pump 40 and 400. Outside diameter is 4".

Built-in pressure gauge takes the guesswork out of inflating your boat, kayak or board. This low-volume, two-hand pump lets you inflate to pressures up to 20 psi.

This 12-volt pump is capable of inflating to 1.5 psi for a fast and easy inflation. For many inflatable crafts you'll still want to have a hand pump for top off to full pressure and to take along with you on the water.

15 pounds per square inch (psi) air pressure in NRS SUP boards gives you a rock-solid board. Hook the K-Air up to your K-Pump and day dream while you pump away.
