CMP CM51525Z Frigo Zinc Boat Anode Saltwater Corrosion Protection

The CMP CM51525Z is a zinc sacrificial anode designed specifically for use on Frigo marine components. Engineered for saltwater use only, this small-profile zinc anode provides reliable electrochemical corrosion protection by sacrificing itself to protect metal boat parts from galvanic corrosion.

Key Features:

• Material: Zinc — the correct alloy for saltwater marine environments
• Inner Diameter: 0.30 inches
• Outer Diameter: 1.36 inches
• Height: 0.28 inches
• For Use In: Saltwater only
• Compact disc/ring-style anode for precise fitment on Frigo marine components
• Provides sacrificial cathodic protection to prevent galvanic and electrolytic corrosion

Sacrificial zinc anodes are a critical part of any saltwater vessel's corrosion protection system. As the least noble metal in the galvanic series among common marine metals, zinc corrodes preferentially, protecting your boat's more valuable metal components. Replace regularly as part of routine marine maintenance when the anode has diminished by approximately 50%.
