Product Details

The CMP CMEZ3 is a sacrificial zinc pencil anode engineered to protect marine engine cooling systems from galvanic corrosion. Designed exclusively for saltwater use, this anode is installed directly into the engine's raw water cooling passages, where it actively corrodes in place of critical metal components, extending the life of your engine block, heat exchangers, and associated hardware.

Key Features:

  • Material: High-purity zinc for maximum galvanic protection in saltwater environments
  • Outside Diameter: 3/4 inch
  • Length: 2 inches
  • Thread Size: 1/2 inch UNC (Unified National Coarse)
  • Application: Marine engine raw water / engine cooling system
  • Environment: Saltwater use only — not recommended for freshwater or brackish water

Zinc pencil anodes like the CMEZ3 should be inspected regularly and replaced when approximately 50% consumed to maintain continuous corrosion protection. CMP (Canadian Metal Parts) is a trusted manufacturer of marine sacrificial anodes used by boaters and marine professionals worldwide.
