Ozek Magnesium Anode Rods for Water Heater 9.25" ¾" NPT 2-Pack — RV & Home Tank Protection

Ozek 9.25" magnesium anode rod 2-pack with ¾" NPT threads protects water heater tanks by sacrificially attracting corrosive elements to extend tank life.

If you rely on a tank-style water heater—whether in an RV or a fixed installation—internal corrosion gradually eats away at the steel liner. An anode rod is a replaceable sacrificial metal that oxidizes instead of the tank, slowing rust and delaying costly tank failure. This Ozek kit supplies two magnesium anodes sized and threaded to fit many RV water heaters and select Suburban and Mor-Flo models.

How do these anode rods protect a water heater tank?

Magnesium anode rods act as the preferred sacrificial metal: they corrode first, diverting destructive electrochemical activity away from the steel tank. Regularly replacing the anode maintains that protection, reducing sediment-driven corrosion and prolonging functional life.

• Uses high-purity magnesium to attract corrosive ions.
• Designed for sacrificial corrosion, not structural support.
• Helps reduce internal rust and pinhole leaks when replaced periodically.

Will these rods fit my heater and how do I install them?

The rods are 9.25 inches long with ¾" NPT external threads, compatible with many RV tanks and specific Suburban 232767 and Mor-Flo models. A 1-1/16" socket is required to remove the old rod and tighten the new one; PTFE tape is included to seal the threaded connection.

• 9.25" length accommodates compact RV tank openings.
• ¾" NPT threads match common anode ports—verify your tank specs first.
• Comes with PTFE tape and requires a 1-1/16" socket for installation.

Why choose magnesium over aluminum or zinc anodes?

Magnesium is a highly reactive metal that offers strong sacrificial protection in freshwater systems and cooler water temperatures. It tends to provide more aggressive corrosion protection than aluminum blends but can deplete faster, so monitoring and periodic replacement are recommended.

• Optimal for potable water systems in RVs and homes with soft water.
• Stronger electrochemical activity protects steel tanks effectively.
• Inspect annually; replace when largely consumed to maintain defense.

Who is this for? The Ozek 2-pack of 9.25" magnesium anode rods is designed for RV owners, DIY-minded homeowners, and service technicians who need a compact, ready-to-install sacrificial anode for common ¾" NPT water heater ports. It’s especially suitable for those using Suburban 232767 and Mor-Flo tanks or anyone looking to keep a spare anode on hand for preventative maintenance. Remember: while Ozek is a US business, the anodes are manufactured overseas—this kit includes two rods plus PTFE tape so you can replace anodes promptly and reduce the risk of premature tank failure.
