Rheem-Ruud AP11525BD-2 Magnesium Anode Rod 0.840" Dia x 50-3/8" Length

The Rheem-Ruud AP11525BD-2 is an OEM magnesium anode rod designed to protect water heater tanks from corrosion and extend service life. Measuring 0.840 inches in diameter and 50-3/8 inches in length, this rod is a genuine Rheem-Ruud replacement part engineered to fit compatible Rheem and Ruud water heater models.

Anode rods are the primary defense against tank corrosion in water heaters. Magnesium, being electrochemically active, preferentially attracts and absorbs corrosive elements present in the water supply — protecting the steel tank walls from rust, scale buildup, and premature failure. As the magnesium material sacrificially corrodes over time, the tank interior remains protected.

Key Features:

• Material: Magnesium — provides superior sacrificial corrosion protection
• Diameter: 0.840 in. (0.84")
• Length: 50-3/8 in.
• OEM Rheem-Ruud genuine replacement part
• Compatible with Rheem and Ruud gas, electric, and heat pump water heaters (verify fit by model)
• Regular replacement helps extend water heater tank life and prevent leaks

Inspect and replace your anode rod periodically as part of routine water heater maintenance. A depleted anode rod can no longer protect the tank, leading to accelerated corrosion and potential tank failure. Using a genuine Rheem-Ruud magnesium anode rod ensures proper fit and continued protection.
