Tecnoseal 00271 Bolt On With Strap Bar Hull Anode

A bar anode similar to ZD78B anodes and is manufactured to US MIL Spec by Tecnoseal in Italy, one of the world's leading suppliers of sacrificial anodes for cathodic protection in the leisure boat market.

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

Galvanic corrosion 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.

Anode deterioration must be monitored carefully and replaced every year when doing the antifouling/launching or when the anode is 75% dissolved.

The choice of anode depends of the nature of the water:

• Saltwater: Zinc Anodes or Aluminium Anodes
• Freshwater: Magnesium Anodes
• Brackish Water: Aluminium Anodes
