CE-2D Complete Aluminum Pencil Anode with Plug — Replaces E-2D, 1/2" NPT

Need an E-2D replacement? The CE-2D is a complete aluminum pencil anode assembly with a stainless steel 1/2" NPT plug, ready to install in compatible marine heat exchanger and cooling system applications. It provides reliable corrosion protection in salt, brackish, and fresh water.

Aluminum performs better than zinc in heat exchanger applications, helping maintain effective corrosion protection across a wider range of water conditions. The Securecore® steel core helps prevent worn anode sections from breaking away and blocking internal cooling passages.
