Blue Lightning Rods Magnesium Flexible Anode Rod
Residential with Hex Head

Residential Blue Lightning Magnesium Flexible Anode Rod

This is the Hex Plug model of the Blue Lightning Magnesium Flexible Anode Rod. This model has a length of 44 inches, a diameter of .75 inches, and 3/4-14 NPT thread size (This sizing should be standard for the bulk of residential water heaters). The rod is broken down into four separate segments. Each segment is Magnesium on a steal rod core. The segments are attached via copper or stainless steel couplers and 301 stainless steel braided wire. 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.
