## Overview

The Blue Lightning Magnesium RV Anode Rod is a 9.5-inch, 3/4-14 NPT threaded, lead-free rod made with over 95% pure magnesium on a steel core. Designed for Suburban and Morflo water heaters, it prevents corrosion and sediment buildup, enhancing water heater longevity and delivering health and environmental benefits.

## Description

This is the Recreational Vehicle model of the Blue Lightning Magnesium Anode Rod. This model has a length of 9.5 inches, a diameter of .75 inches, and 3/4-14 NPT thread size (This sizing should fit Suburban and Morflo water heaters). This anode rod is made of Magnesium on a steal rod core. All of our Anode Rods are lead free! This rod is over 95 percent magnesium and one of the purest on the market. The magnesium dissolves into your water over time instead of breaking down and leaving nasty sediment at the bottom of the water heater tank. The Magnesium also provides many health and environmental benefits as it passively dissolves in your hot water supply. The Blue Lightning Magnesium Anode Rod should be checked on an annual basis and in most cases replaced every other year depending on the rate of deterioration.
