    Zinc Rods

    Image of Product. Front orientation. Zinc. Zinc Rods.
    Cut and thread discs and other parts that draw corrosion away from nearby metal in water tanks, heat exchangers, and marine applications. These rods are made almost purely of zinc and meet MIL-A-18001, which means they break down faster than other types of metal. Attach your parts directly to the materials you want to protect.
