AE-1D Aluminum Pencil Anode – Anode Only

Protect your engine’s heat exchanger from corrosion with the AE-1D aluminum pencil anode. Designed as a replacement for multiple OEM-style pencil anodes, it provides reliable corrosion protection for heat exchanger applications across a wide range of marine engines.

Aluminum anodes perform better than zinc in heat exchanger applications, helping provide effective corrosion protection for critical engine components. The Securecore® central steel core helps prevent a worn anode end from breaking away and blocking critical waterways.
