Also known as sacrificial anodes, pencil anodes, or engine anodes, these zinc rods are consumed by any electrolytic action that would otherwise attack and corrode your valuable equipment. Our zinc rods protect engines, heat exchangers, pipes, condensers, water cooling jackets and so on from corrosion and scaling in hot water applications and may be used in cold water as well. Ideal for use in salt water. All zinc alloys are made to the MIL-A-18001K spec (aka ASTM B-418 Type 1)

We have 5 types of Pencil/Engine Zinc Anodes, follow the links below to see each one:
Type P Anodes function the same as the Type C but have NC threads and do not have the steel wire.
Please note that while Types C and P are not interchangeable, you can use a complete C in the place of a P.
Cor-In Anodes are the Most Popular!
