Diximus RV Water Heater Anode Rods Set of 2 — 3/4" NPT Magnesium 9.25" for Suburban & Mor-Flo, Includes PTFE Tape

Diximus magnesium anode rod pair protects RV water heater tanks from corrosion and extends service life for Suburban and Mor-Flo systems. Keeping an RV water heater in good condition saves time, money, and inconvenient repairs on the road. These Diximus anode rods are designed specifically to slow tank corrosion by acting as a sacrificial metal inside the heater, diverting corrosive activity away from the steel tank. Supplied as a set of two rods plus PTFE tape, they fit standard 3/4" NPT openings used by many Suburban and Mor-Flo units and drop into place with a 1-1/16" socket.

How do these anode rods protect my RV water heater?

The Diximus rods are made from magnesium, a metal that preferentially corrodes in place of the steel tank. As the magnesium corrodes, it neutralizes destructive electrochemical reactions and removes minerals that would otherwise attack the tank lining.

• Sacrificial magnesium composition captures corrosive action before it reaches tank steel.
• Dual-rod package allows staggered replacement intervals for continuous protection.
• Non-toxic material reduces concerns versus some aluminum-based rods.

Will these rods fit my Suburban or Mor-Flo water heater?

Yes — these anode rods measure 9.25 inches overall with a standard 3/4" NPT threaded connection, matching the specifications used by many Suburban and Mor-Flo RV water heaters. They are compatible with common Suburban model families (D, DE, DEL, DEM), and work with any tank using a 3/4" anode port.

• Length: 9.25 inches to reach protective zones inside the tank.
• Thread: 3/4" NPT for direct fit into factory anode openings.
• Compatible models listed include Suburban D/DE/DEL/DEM and most Mor-Flo units.

How difficult is installation and what tools or parts are included?

Installation is straightforward and typically takes only a few minutes for someone comfortable with basic RV maintenance. Use a 1-1/16" socket (not included) to loosen and tighten the existing anode; Diximus supplies a roll of PTFE tape to seal the threads and prevent leaks.

• Includes two magnesium anode rods and one roll of PTFE tape for a secure seal.
• Requires a 1-1/16" socket for installation, plus basic hand tools.
• Quick swap design minimizes hot-water downtime during replacement.

Why choose magnesium over aluminum or aluminum-zinc anode rods?

Magnesium anodes corrode more readily than aluminum, offering robust protection in freshwater and typical RV water conditions. They are also considered safer in terms of material composition and provide effective sacrificial action that helps reduce scale and corrosion inside the tank.

• Higher electrochemical activity means faster sacrificial protection of tank steel.
• Made from non-toxic magnesium, avoiding some concerns linked to aluminum alloys.
• Designed for longer-lasting performance and reliable tank defense on the road.

Who is this for These Diximus anode rods are ideal for RV owners, fleet maintainers, and DIY technicians who want a reliable, easy-to-install corrosion protection upgrade for their Suburban or Mor-Flo water heaters. If you service your RV regularly, prefer magnesium anodes for stronger sacrificial action, or need a two-rod kit plus PTFE tape for immediate replacement, this set provides a practical, cost-effective solution to extend tank life and reduce repair risk while traveling.

FAQ

Q: How often should I replace the Diximus magnesium anode rod?

A: Inspect annually; replace when more than 50% depleted or every 2–4 years depending on water chemistry and usage.

Q: Does this kit include all parts needed to install?

A: The kit includes two magnesium rods and PTFE tape; a 1-1/16" socket is required but not included.
