Product Description
Marine Grade Magnesium Anode Rod 42" for Boat and Yacht Water Heaters
The WNRLN WMR-MG42 is engineered for the demanding marine environment. Boat and yacht water heaters face accelerated corrosion due to saltwater exposure and frequent temperature cycling. This marine-grade magnesium anode rod features an AZ63B alloy formulation with enhanced resistance to aggressive electrolyte conditions, plus an epoxy coating on the steel core thread area to prevent galvanic seizing—a common problem in salt-air environments.
Key Features
- Marine Optimized Alloy: AZ63B formulation resists saltwater electrolyte degradation
- Anti-Seize Thread Coating: Epoxy-protected threads prevent galvanic bonding
- VCI Packaging: Volatile Corrosion Inhibitor bag for long-term marine storage
- ABS Type Approved: Certified by American Bureau of Shipping
- Universal Marine Fit: 5/8 NPT matches most marine water heater ports
