Majoni Fender & Buoy Brass Replacement Inflation Valve

The Majoni Fender & Buoy Brass Replacement Inflation Valve is an original-style service component for compatible Majoni inflatable fenders and buoys. It replaces a leaking, corroded or damaged valve while retaining the manufacturer’s self-sealing brass inflation system.

The valve has an M3 internal service thread that allows a suitable M3 bolt to be used as a removal and installation aid. Compatibility must be confirmed from the existing valve and fender body before removal.

What Is the Majoni Replacement Valve Used For?

It restores the inflation and non-return function of a compatible Majoni fender or buoy when the existing brass valve is damaged, corroded or leaking. It is not intended to repair a split body, damaged eye or failed moulding.

• One Majoni brass replacement inflation valve

What Is Not Included?

• M3 removal bolt
• Pliers or installation tools
• Inflation adaptor
• Pump or compressor
• Sealant unless specifically required by the product service method
• Fender or buoy

How Do I Confirm Compatibility?

• Compare the existing valve shape and dimensions with the replacement.
• Confirm the product is a Majoni fender or buoy using the standard brass-valve system.
• Do not force the valve into a different thread or socket.
• Replace the complete fender if the valve seat or surrounding body is damaged.

How Is the Valve Removed and Fitted?

1. Deflate the fender completely.
2. Thread a suitable M3 bolt into the valve service thread.
3. Grip the bolt carefully with pliers and withdraw the old valve without damaging the body.
4. Inspect and clean the valve seat.
5. Fit the replacement squarely and secure it using the appropriate service method.
6. Inflate gradually and check for leakage with a mild soap solution.

Inflation and Safety

After fitting, inflate gradually to approximately 0.2 bar / 2.9 psi or the pressure stated for the product. Never insert a needle or pin into the valve. Do not use a valve replacement to return a structurally damaged fender or buoy to service.

Maintenance

• Rinse the valve after exposure to salt water.
• Check periodically for green corrosion, looseness or leakage.
• Keep grit and paint away from the sealing surface.
• Use the correct Majoni adaptor for future pressure adjustment.
