42" Magnesium Anode Rod Compatible with Rheem and A. O. Smith Water Heaters

Key features

• Water Heater Anode Rod Replacement: Compatible with select Rheem, A. O. Smith, State, Reliance, Richmond and Giant tank water heaters using a 3/4" NPT port. Confirm the original rod, tank depth and overhead clearance before ordering.
• Sacrificial Magnesium Protection: This magnesium anode rod for hot water heater tanks corrodes before the steel tank, helping reduce internal rust and costly premature damage. Replace a depleted rod to restore a key layer of protection.
• 42" Solid Anode Rod: The one-piece magnesium anode rod provides continuous sacrificial material for compatible tanks. Measure tank depth and overhead clearance first; this rigid design is not a flexible segmented rod.
• Complete Socket Kit: Includes one 42" magnesium anode rod, one 1-1/16" socket and PTFE tape, giving you the key replacement items in one package and saving the time and cost of sourcing them separately.
• Fit Beyond Gallon Size: For 40- or 50-gallon water heaters, tank capacity alone does not confirm fit. Verify the 3/4" NPT port, usable depth and overhead space so the replacement can be completed without an avoidable return.

Free shipping included. 30-day hassle-free returns.
