Shaft Anode – Zinc – 20mm 38225

Description

Shaft Anode

The anodes selected by Plastimo are manufactured according to the ISO 9002 specifications and are submitted to stringent control.

When your boat’s hull is submerged, anodes protect the various metal components (propeller shaft, keel, rudder, engine) from the deterioration caused by galvanic corrosion.

Galvanic corrosion (also called electrolyte) is the deterioration of metal which occurs when dissimilar metals are joined together by a conductor in an electrically conductive fluid : the least noble metal (the anode) dissolves while the most noble metal (the cathode) remains protected. The choice of the anode composition is also very important according to the nature of the water :

• Saltwater: Zinc anode
• Freshwater: Magnesium anode
• Brackish water: Aluminium anode

Specifications

• Internal diameter: 20mm
