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. A reinforcing steel core holds zinc in place until it's completely consumed. They come with NPT hex brass plugs. Zinc rods protect from corrosion and scaling in hot water applications. Ideal for use in salt water. They can also be used in cold water.
