Tecnoseal TEC-DOK Zinc Sea Strainer Anode Plate 81x32x10 mm
The Tecnoseal TEC-DOK is a rectangular zinc sacrificial anode plate listed for marine sea strainer applications. It provides a replaceable zinc element to help reduce galvanic corrosion of compatible metallic components when correctly installed.
The anode features a rectangular body with rounded corners, measuring 81 mm (3.19 in) in length, 32 mm (1.26 in) in width and 10 mm (0.39 in) in height. Two recessed mounting holes are positioned along the longitudinal axis of the plate.
The mounting holes have a diameter of 6.5 mm (0.26 in) and a centre-to-centre spacing of 46 mm (1.81 in). The Tecnoseal TEC-DOK weighs 0.15 kg (0.33 lbs).

Rectangular Plate Design and Mounting
The Tecnoseal TEC-DOK features a compact rectangular profile with rounded corners and two recessed mounting holes. The holes are spaced 46 mm apart, measured between their centres, with a specified diameter of 6.5 mm.
Before ordering, verify the 81 × 32 × 10 mm body dimensions, mounting hole spacing and hole diameter against the original anode.
Marine Galvanic Corrosion Protection
The zinc material acts as a sacrificial element, helping reduce galvanic corrosion of associated metallic components when installed with the required electrical contact.
The suitability of the anode depends on the particular equipment, operating water conditions and existing corrosion protection arrangement.
Inspection and Replacement
Sacrificial zinc anodes gradually lose material during service. Periodic inspection is recommended, with replacement when the anode is sufficiently consumed.
Installation should follow the relevant equipment maintenance instructions and maintain electrical contact with the protected metallic component.
Supply: One Tecnoseal TEC-DOK zinc sacrificial rectangular plate anode.
