Unbranded 3/4 in. NPT X 42 in. 3-Section Aluminum Anode Rod

Anode rods are the most important line of defense in increasing water heater tank life and preventing leaks. These devices work because the metal in the rod is sacrificed so the tank does not corrode. The anode should be checked and replaced every couple of years. This Everbilt 3/4 in. NPT X 42 in. 3-Section Aluminum Anode Rod features 3-section flexibility for easy installation.
