Magnesium Anode Rod for Electric Water Heater

Our Magnesium Anode Rod for Electric Water Heater features a high-purity magnesium composition (≥99.8%), delivering exceptional sacrificial protection by attracting corrosive elements away from your water heater’s inner tank. This premium-grade construction effectively prevents rust and extends your appliance’s lifespan by up to 50%. It is available in three universal lengths (10”, 12”, 14”) with standard NPT thread sizes (½”, ¾”), ensuring compatibility with 95% of residential and commercial electric water heaters, including most tank-style models from leading brands.  

The rod’s thickened magnesium alloy core and special anti-oxidation coating provide outstanding durability, resisting premature wear and maintaining peak performance for 2–3 years—double the lifespan of ordinary aluminum-magnesium rods. Installation is quick and tool-free; simply screw it into the heater’s designated anode port for immediate protection.  

In addition to corrosion prevention, this anode rod helps neutralize harmful minerals such as calcium and magnesium, reducing sediment buildup and improving overall water quality. By keeping the tank clean, it enhances heating efficiency, shortens recovery times, and lowers energy consumption—ultimately cutting your electricity costs.  

Whether you’re performing routine maintenance or replacing an old, worn rod, this magnesium anode rod is an essential investment to protect your water heater, prevent costly leaks, and ensure a reliable supply of hot water for years to come.
