Raritan Magnesium Anode f/6-Gallon Water Heater

The Raritan Magnesium Anode for 6-Gallon Water Heater is a corrosion-prevention component designed specifically for Raritan's 6-gallon marine water heating systems. Magnesium anodes function as sacrificial electrodes, corroding preferentially to the steel tank interior and protecting it from oxidation and rust—a critical maintenance item in saltwater environments where galvanic corrosion threatens tank integrity.

This anode measures 16-1/8 inches in length and features a stainless steel fitting for durability and reliable connection to the tank. The magnesium alloy composition is optimized for freshwater and brackish water applications, offering faster corrosion rates than aluminum alternatives—meaning more aggressive protection in systems exposed to mineral-rich or slightly acidic water conditions. Proper anode replacement extends tank life by years and prevents costly water heater failures caused by internal rust perforation.

This replacement anode is essential for boat owners, RV operators, and marine system technicians maintaining Raritan water heaters. Anodes require periodic inspection and replacement—typically every 3 to 5 years depending on water chemistry and usage—making this OEM part a routine but non-negotiable maintenance component. Having the correct Raritan magnesium anode in stock ensures uninterrupted hot water service and prevents emergency system shutdown due to tank failure.

Using the genuine Raritan part number 1790610 guarantees fit and compatibility with Raritan's 6-gallon tank specification. Aftermarket or incorrect anode types may not deliver adequate protection or may physically interfere with tank internals, making OEM sourcing the responsible choice for water heater longevity.
