Premium Quality Maintenance & Repair Kit

This Majoni Brass Inflation Adaptor Kit is an essential accessory for any boat owner using Majoni fenders or buoys. Majoni fenders feature a unique internal brass ball-valve system that requires a specific threaded interface for safe inflation. This kit provides a high-quality brass adapter that converts the fender valve to a standard Schrader (car/bicycle) fitting, allowing you to use everyday pumps or compressors without damaging the delicate non-return mechanism.

Additionally, the kit includes four replacement brass valves. These are identical to the original equipment and are used to restore airtight performance if your original valves become clogged with salt, debris, or suffer mechanical wear over time.

RELIABILITY: Manufactured from corrosion-resistant marine-grade brass, ensuring longevity in harsh saltwater environments.

Questions & Answers

Is this a genuine original part?

This kit contains components manufactured to exact Majoni OEM specifications to ensure a perfect fit and reliable seal on all compatible fenders.

How do I replace the valves?

Simply thread an M3 bolt (not included) into the old valve, use pliers to pull the valve out, and then push the new valve into place using the same method.

Why can't I use a football needle?

Majoni valves use a delicate internal ball/flap mechanism. A needle-type adapter can pierce or dislodge the flap, causing the fender to leak permanently. This brass adapter is designed to sit against the valve without damaging it.

Note: Proper inflation pressure for Majoni fenders is 0.2 bar (2.9 psi). You should be able to press the fender wall in slightly with the flat of your hand. Do not over-inflate.
