Tecnoseal Castoldi Large Engine Washer Anode Ø80 mm

Tecnoseal Castoldi Large Engine Washer Anode Ø80 mm – Zinc, Aluminium or Magnesium

The Tecnoseal 02404 series consists of large sacrificial washer anodes designed for Castoldi marine engines. These anodes help protect compatible metallic engine components against galvanic corrosion.

The anode features a cylindrical body with a recessed central mounting hole. It measures 80 mm (3.15 in) in outer diameter and 50 mm (1.97 in) in height. The central mounting recess has a diameter of 30 mm (1.18 in), while the through-hole measures 12 mm (0.47 in).

Three material versions are available: zinc (Tecnoseal 02404), aluminium (Tecnoseal 02404AL) and magnesium (Tecnoseal 02404MG). All three versions share identical dimensions and mounting specifications, with different weights depending on the selected sacrificial material.
