Corrosion-Inhibiting Rods and Pads
Also known as sacrificial anodes, these rods and pads protect tanks, water heaters, and heat exchangers from rusting by attracting corrosion that would otherwise damage equipment.
Rods have a steel core covered with zinc or magnesium. They have a threaded pipe connection.
Zinc rods protect against corrosion and scaling in salt water and fresh water.
Zinc alloy pads provide corrosion protection in salt water.
Rectangular pads have a mounting wire.
Circular and square pads have a mounting hole.
