Ao Smith 100210064 Aluminum Anode Rod 23in 5in Nipple

Product Description

The AO SMITH 100210064 is an aluminum anode outlet rod designed for use in residential and light commercial water heaters. Anode rods protect the water heater tank lining from corrosion through a sacrificial electrochemical process — the aluminum material corrodes preferentially, extending tank service life. This rod measures 23 inches in total length with a 5-inch nipple, making it a direct-fit replacement for compatible AO SMITH water heater applications. Installation is typically performed by licensed plumbers during routine water heater maintenance or as part of a service call addressing anode depletion.

This anode outlet rod is used in water heater maintenance service on residential and light commercial storage-tank water heaters. Anode rods are a consumable maintenance item, typically inspected every two to four years and replaced when the core wire is exposed or the rod is significantly depleted. The aluminum construction makes it suitable for installations where water chemistry favors aluminum over magnesium anode material. It is intended as a replacement part and fits into the designated anode port on compatible AO SMITH tank water heater models.

Key Features

• Aluminum construction provides sacrificial corrosion protection for the water heater tank
• 23-inch total length suits standard residential water heater anode ports
• 5-inch nipple for proper reach and installation depth
• OEM replacement part designed to restore original corrosion protection performance
• Aluminum alloy material is suited for water conditions where aluminum anodes are preferred

Compatibility

Designed as an OEM-style replacement anode outlet rod for compatible AO SMITH storage-tank water heaters requiring a 23-inch aluminum anode with a 5-inch nipple.

Installation Notes

Anode rod replacement is performed by a licensed plumber. Before servicing, shut off the cold water supply and power or gas to the water heater, and relieve tank pressure before removing the existing rod. A 1-1/16-inch socket and breaker bar are commonly required for anode removal, as rods often seat tightly after extended service. Apply thread sealant tape to the threads and torque to the water heater manufacturer specification referenced in the service documentation.
