About Cor-In 1 Inch NPT X 8 Inch Complete Zinc Pencil
1" NPT Brass Plug x 8: length of zinc rod complete. Wrench size 1 3/8". 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. 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.
