This Lochinvar anode is a secondary sacrificial component designed to protect the internal surfaces of water heaters and boilers from corrosion. The anode achieves this by attracting corrosive elements present in the water, thereby sparing the tank's material. Made from magnesium, a metal known for its superior sacrificial properties, it ensures prolonged lifespan of your heating equipment. It is compatible with various Lochinvar models and is easy to install due to its rod-like structure and threaded top. This product measures 0.84 inches in diameter and 44 inches in length, making it suitable for large-capacity tanks.
