Inflation Guide

In all our fenders and buoys we use a unique strong brass valve for easy inflation and deflation. The best way to inflate a fender is just pushing air pressure from a compressor with a flat head against the valve and the fender will inflate. It also is possible to inflate the fender with a bicycle or car pump with the special Majoni adapter. Do not use a handset with a pin to inflate, because the pin can damage the valve. Best inflation pressure is 0.2 bar / 2.9 psi. This is the pressure where you should be able to press the body of the fender visible easy with your flat hand.

Majoni Adapter

The Special Majoni valve Adapter can be used for:

  • Inflating with a bicycle pump
  • Inflating with a car pump
  • Deflating the fender when pumped too hard
  • Pulling out the valve with the pulling aid
  • Putting a valve back with the pushing aid

Valve and Adapter

Our unique brass valve for easy inflation and deflation. With the Majoni adapter you can inflate your fender easy with a bicycle or car tire pump. It is not necessary to use an adapter. With enough air pressure, with something like a compressor, the valve will open, and the fender will inflate. To replace a valve, use a bolt M3 and pull it out with a pair of tongs or use the Majoni Adapter with pulling aid
