Marine Pencil Anodes & Zincs

Pencil zincs are typically used to protect heat exchangers and can usually be found attached to a brass plug within the exchanger. They should be checked at least once a year and replaced if less than 50% of the anode remains. To replace, simply unscrew the old pencil anode from the brass plug and replace it with a new one. Fisheries Supply carries a variety of marine pencil zincs from trusted brands like Sea Shield Marine and Martyr, so shop today and protect your boat!
