Martyr Anodes CMEZ2 Zinc Pencil Anode 5/8" x 2" (Plug Not Included)

The Martyr Anodes CMEZ2 is a replacement zinc pencil anode designed for marine engine cooling systems. This sacrificial anode protects your engine's cooling passages from galvanic corrosion by attracting corrosive electrical currents that would otherwise attack more expensive metal components.

Key Features:

• Zinc alloy construction for saltwater and brackish water applications
• Dimensions: 5/8" diameter x 2" length
• Pencil anode style for easy replacement
• Compatible with standard engine cooling system housings
• Anode only - brass plug sold separately

Regular inspection and replacement of pencil anodes is essential for maintaining your engine's cooling system integrity. Replace when anode material is depleted by 50% or shows significant deterioration. This anode fits into existing threaded brass plugs commonly found in marine engine heat exchangers, oil coolers, and transmission coolers.
