69719 is an Aqua Pro magnesium anode rod designed for compatible Atwood water heaters. It measures 4-1/2" long and features a 1/2"-14 male pipe thread (MPT) connection. The lead-free anode helps protect the water heater tank from corrosion by attracting corrosive elements in the water. It is designed as a replacement for the existing MPT drain plug. Verify the water heater brand and drain fitting specifications before ordering.
