3/4" x 2" Hot Water Outlet Anode Rod, NPT x Nipple

OEM Magnesium Anode Rod for Corrosion Protection in Residential Tank Water Heaters

The Bradford White 415-47776-05 Hot Water Outlet Anode Rod is a factory-specified replacement component designed to protect the steel tank interior from galvanic corrosion. This model combines the function of a standard sacrificial anode with the hot water outlet port, streamlining tank design and reducing the number of service points.

Constructed from magnesium for high reactivity, this anode is engineered to extend the service life of residential water heaters by actively corroding in place of the tank’s interior surfaces. Routine inspection and scheduled replacement are critical to preventing premature tank failure due to aggressive water conditions or prolonged anode depletion.

Product Configuration and Use

• Part Number: 415-47776-05
• Function: Combined anode rod and hot water outlet
• Material: Magnesium core for high-rate electrochemical protection
• Dimensions: 3/4" NPT x 2" nipple, 38.13" overall length, 0.840" OD
• Thread Size: Standard 3/4" NPT outlet connection

Model Compatibility

This anode rod is designed specifically for Bradford White water heater models including:

• MI40R6DS-15BN, CX, SX
• MI50L6DS-15BN, CX, SX

Always confirm part number compatibility with the unit’s serial or model number and manufacturer documentation prior to installation.

Installation Considerations

This anode rod is installed through the hot outlet port at the top of the tank and may require removal of the existing nipple. Replacement should be completed by a licensed plumbing contractor to ensure correct torque, sealing, and dielectric separation where required. Thread sealant or approved Teflon tape is recommended for leak-free installation.

Replacement is typically recommended every 3 to 5 years depending on water chemistry. In aggressive or softened water environments, inspection intervals should be reduced to 12–24 months to avoid tank exposure after full anode depletion.

Performance Benefits

• Corrosion Control: Sacrificial magnesium core protects tank lining and weld seams
• Hot Outlet Integration: Combines two service points for efficient design
• High Reactivity: Magnesium reacts more readily than aluminum or zinc, offering superior protection in many water conditions
• Service Life Extension: Helps prevent tank rupture due to unseen internal deterioration

Contractor Use Case

For service calls involving discolored hot water, odor complaints, or tank maintenance, this OEM outlet rod provides a direct replacement solution that preserves system longevity. Stocking this part ensures readiness for tank servicing in models using integrated outlet-anode designs. Use only Bradford White-approved anodes to maintain warranty compliance and correct tank performance characteristics.
