CE-3A Complete Aluminum Pencil Anode with Plug — Replaces E-3A / CME-3S

Protect your marine heat exchanger and cooling system with the CE-3A complete aluminum pencil anode. Designed as a replacement for E-3A and CME-3S anodes, this assembly includes an aluminum pencil anode with Securecore® steel core and a stainless steel 3/4" NPT plug.

Aluminum performs better than zinc in heat exchanger applications, providing reliable corrosion protection across salt, brackish, and fresh water. The Securecore® steel core helps prevent worn anode sections from breaking away and blocking internal cooling passages.
