Tecnoseal Aluminum Bolt-On Hull Anodes are designed to protect your vessel in freshwater environments. Made from an aluminum-indium-zinc alloy (Mil-A-24779 SH), these anodes are ideal for vessels with steel, fiberglass, wooden, or aluminum hulls. Please note, attachment kits, including pins and bolts, are sold separately, ensuring secure mounting to various hull materials. Tecnoseal zinc anodes are manufactured to meet US military standards (A-18001 K), guaranteeing effective cathodic protection.
Proper installation is essential for maximizing protection. Ensure all metal parts have direct contact with the anode. For fiberglass hulls, connect supplied bolts by wire to metal components for optimum protection. All Vetus anodes have a protective paint layer on the mounting side to avoid hull paint damage.
Why Choose Aluminum Anodes?
Aluminum anodes are recommended for vessels operating in fresh waters, where their lower electrochemical potential offers effective protection. They are suitable for boats in both saltwater and slightly saline environments, though they may experience faster wear in salty conditions. We advise against magnesium anodes due to their lower electrochemical potential, which may impact the hull coating.
