CE-1D Complete Aluminum Pencil Anode with Plug — Replaces E-1D / CME-1D

Protect your engine’s heat exchanger and cooling system from corrosion with the CE-1D complete aluminum pencil anode. Designed as a replacement for the E-1D and CME-1D, this assembly includes the aluminum pencil anode and stainless steel 3/8" NPT plug for convenient installation.

Aluminum anodes perform better than zinc in heat exchanger applications, helping provide consistent corrosion protection across saltwater, brackish water, and freshwater environments. The Securecore® steel core helps prevent a worn anode end from breaking away and blocking critical waterways.
