A.o. Smith 100109434 Magnesium Anode Rod Kit 16 in

Product Description

The A.O. SMITH 100109434 is a magnesium anode rod kit designed as a direct replacement component for residential water heaters. Measuring 16 inches in length with a 0.84-inch diameter and a hex-style end fitting, this rod is installed inside the water heater tank to protect the steel lining from corrosion through a sacrificial electrochemical process. As the magnesium material gradually depletes, it draws corrosive elements away from the tank wall, extending the service life of the unit. Plumbers and water heater technicians install this rod as part of routine maintenance or when performing a water heater service call.

This anode rod kit is used in residential water heater applications where a replacement magnesium anode is required. It is appropriate for installations where the existing anode rod has corroded significantly or has been consumed beyond serviceable condition. The hex end design allows for removal and installation using a standard socket wrench, making it compatible with typical top-entry anode rod ports found on tank-style water heaters.

Key Features

• Magnesium construction provides effective sacrificial corrosion protection for steel water heater tanks
• 16-inch length suits standard residential tank configurations
• 0.84-inch diameter fits common anode rod port dimensions
• Hex end fitting allows installation and removal with a standard socket wrench
• OEM-style replacement part designed to restore corrosion protection to aging water heater tanks

Compatibility

Designed as an OEM-style replacement anode rod for A.O. SMITH tank-style water heaters requiring a 16-inch magnesium anode rod with a hex end fitting.

Installation Notes

Anode rod replacement is typically performed by a licensed plumber. Before servicing, shut off the cold water supply and disconnect power to the water heater or turn the gas valve to the pilot position. Drain a portion of the tank to relieve pressure before attempting to remove the existing rod. Apply thread sealant tape to the threads before installing the new rod and do not overtighten, as the port threads on older tanks can be fragile.
