Zinc anode - Shaft nut Ø60mm

Zinc anode - Shaft nut Ø60mm Zinc anode for ø40mm shaft line, fixed with 4 screws. The anode is a device that protects important metal equipment in contact with water from corrosion. This is known as a sacrificial anode. Anodes must be cleaned and replaced regularly, as they are no longer effective after 60% wear. In salt water, choose zinc alloy or aluminium alloy anodes. Aluminium has the advantage of being lighter and less polluting. In freshwater, magnesium anodes are preferable.
