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.\n\n\u003ch3\u003eHow do these anode rods protect my RV water heater?\u003c\/h3\u003e\n\u003cp\u003eThe Diximus rods are made from magnesium, a metal that preferentially corrodes in place of the steel tank.
