This is a list of the most common Caterpillar original part numbers in ascending order, and their corresponding aftermarket equivalent. Please note, most engine anodes are produced in zinc.

Tecnoseal is one of the world leaders in the cathodic protection field. With over 30 years of experience, Tecnoseal’s main headquarters in Tuscany, Italy manufactures and sells Zinc, Aluminium and Magnesium sacrificial anodes and systems for active cathodic protection.

People often confuse anodes with the base metal they are made of. A zinc anode does not just contain zinc, but a range of other carefully quantified elements. The same applies to the aluminium and magnesium versions. This ensures each anode is effective at protecting underwater structures from corrosion.
