Martyr Engine Cooling Anodes

(27 products)

Selection advice & manufacturer guides

Browse pencil-style anodes and related replacements for engine cooling-system applications. Confirm the equipment reference, anode dimensions and threaded connection where specified. A replacement anode element and an assembly with a plug are different products; check the individual listing before ordering.

Martyr recommends aluminum for saltwater and brackish water, magnesium for freshwater, and zinc for saltwater. Follow your equipment manufacturer's requirements and compare exact part numbers and applications.
