ONENESS 369 RV Water Heater Anode Rod - 2-Pack, Magnesium, 9.25-in x 3/4-in NPT, Suburban Compatible, 2-Year Warranty

Keep the hot water flowing on the road with ONENESS 369 RV Water Heater Anode Rod. This 2-pack of magnesium rods is designed to shield Suburban water heaters from tank corrosion, helping preserve comfort during trips and reducing unexpected cold showers. With a 2-year warranty, you can travel with more confidence, knowing a spare is ready when you need it.

Why magnesium for RV water heaters? Magnesium offers robust cathodic protection and tends to outperform aluminum in varied water conditions often encountered on the road. Our rods are 99.9% pure magnesium, a material choice that emphasizes reliable, road-ready performance while remaining compatible with the way RV water systems age.

Key specs and compatibility

The rod measures 9.25 inches long and 3/4 inch NPT, designed for Suburban water heaters. If you drive an Atwood model, you may need a different size. Before you replace, check model compatibility and the water conditions at your site. For longevity, consider the right nut type: steel nuts suit softer water, while galvanized nuts offer durability in mineral-rich environments.

What you get and how to use it

• 2 magnesium anode rods in each pack for solid replacement planning.
• 99.9% pure magnesium offers strong protection against tank corrosion.
• Designed to defend Suburban water heaters and many RV brands for continued hot water.

As part of a broader maintenance approach, the Ultimate RV Accessories Kit often pairs with this anode rod, including a Dual Hex Wrench for easy replacement and an Oneness 369 RV Water Heater Element with Incoloy 840 for added resistance to heat and corrosion. A dedicated removal tool can simplify maintenance, making it easier to keep water hot on your next trip.

Usage tips and maintenance

• Before replacing, choose the nut type based on water hardness: steel for softer water; galvanized for mineral-rich water.
• Confirm 9.25-in length and 3/4-in NPT threads for Suburban models.
• Keep a spare rod on hand and use the included tools to simplify installation.
