Martyr Anodes Zinc Pencil Anode

The Martyr Anodes Zinc Pencil Anode is a sacrificial zinc anode for marine engines and cooling systems. Pencil zincs, also called pencil anodes or engine zincs, thread into the engine, heat exchanger, or cooling system. They help protect internal metal components from galvanic corrosion, especially in salt and brackish water.

Key Features:

• Made of zinc, which corrodes first so the metal parts around it last longer
• Designed for marine engine, heat exchanger, and cooling system applications
• Threaded design for straightforward installation and replacement
• Available in several diameters and lengths to suit different applications
• Intended to be inspected regularly and replaced once it has mostly eroded

Pencil anodes are a low-cost, routine maintenance item that helps protect valuable engine components. Choose the variant that matches the size your application needs.
