Product Description
The 40-inch magnesium anode rod is specifically formulated to address the two most common water quality complaints in gas water heaters: rusty discolored water and the unpleasant rotten egg smell. Through its active electrochemical properties, this magnesium anode neutralizes sulfur compounds and prevents tank corrosion that causes rust contamination.
The rotten egg odor in hot water is typically caused by sulfate-reducing bacteria that thrive in the warm water environment and react with the anode to produce hydrogen sulfide gas. WNRLN magnesium anode rods are manufactured from high-purity AZ63 alloy with controlled impurity levels, minimizing the reaction that produces hydrogen sulfide while maintaining full corrosion protection. In most cases, switching from an aluminum to a magnesium anode resolves odor issues immediately.
- Odor Elimination Properties: The electrochemical profile of AZ63 magnesium alloy actively reacts with dissolved sulfur, preventing the formation of hydrogen sulfide gas that causes the characteristic rotten egg odor in hot water.
- Rust-Free Hot Water: By sacrificially corroding in place of the steel tank, the anode rod prevents rust particles from contaminating the water supply, ensuring crystal-clear hot water from every tap.
- 3/4 NPT Hex Plug Design: Features a compact hex plug head that fits in tight spaces common around gas water heater flue pipes and venting systems. Compatible with standard 1-1/16 inch sockets.
- Gas Heater Optimized Dimensions: The 40-inch length with 0.84-inch diameter is the most common fitment specification for residential gas water heaters from Rheem, AO Smith, Bradford White, and Kenmore.
- Health-Safe Water Quality: Prevents metallic taste and discoloration, ensuring hot water is suitable for bathing, cooking, and all household uses.
- Lower Maintenance Frequency: Proper anode function reduces sediment buildup at the tank bottom, minimizing the need for periodic tank flushing and extending burner efficiency.
Individually sealed in VCI anti-rust film and packed in display boxes with protective foam end-caps. Multi-pack orders shipped in reinforced export cartons with moisture barrier.
