Protect your marine engine’s cooling system with the PCM Zinc Anode for Heat Exchangers. This sacrificial anode is designed to help reduce galvanic corrosion inside the heat exchanger by corroding first—helping extend the life of critical cooling components and supporting more reliable engine operation in harsh saltwater and brackish-water environments.

Replacing a worn zinc anode is a simple, cost-effective maintenance step that can help prevent premature damage to the heat exchanger and related engine cooling parts. Ideal for routine inspections and seasonal service.
