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 threaded pipe connection.
Zinc rods protect against corrosion and scaling in salt water and fresh water.
Magnesium rods protect against corrosion in fresh water.
Zinc alloy pads provide corrosion protection in salt water.
Aluminum alloy pads last longer than zinc alloy and can be used in fresh water as well as salt water.
Rectangular pads have a mounting wire.
Circular and square pads have a mounting hole.

Zinc Rods
- Yield Strength: Not Rated
- Hardness: Not Rated
- Specifications Met: ASTM B418 Type 1, MIL-A-18001
Cut and thread discs and other parts that draw corrosion away from nearby metal in water tanks, heat exchangers, and marine applications. These rods are made almost purely of zinc and meet MIL-A-18001, which means they break down faster than other types of metal. Attach your parts directly to the materials you want to protect.

Zinc Sheets
Considered commercially pure, this material is 99% zinc.
Use sheets to make parts that draw corrosion away from nearby metal in water tanks, heat exchangers, and marine applications. They meet MIL-A-18001 for chemical composition, so they break down faster than other types of metal. Attach them directly to the materials you want to protect.
