Tecnoseal TEC-21 Zinc Teardrop Plate Anode 136x58x14 mm
The Tecnoseal TEC-21 is a zinc sacrificial teardrop plate anode from the Tecnoseal USA Plate Series. It is designed for marine galvanic corrosion protection, providing a replaceable zinc element to help protect compatible metallic components exposed to water.
The anode features an elongated teardrop-shaped profile with a rounded end tapering towards a narrow tip. Its overall dimensions are 136 mm (5.35 in) in length, 58 mm (2.28 in) in width and 14 mm (0.55 in) in height.
Two recessed mounting holes are positioned along the longitudinal axis of the plate. The holes have a diameter of 8.5 mm (0.33 in) and a centre-to-centre spacing of 41 mm (1.61 in).
Weighing 0.35 kg (0.77 lbs), the Tecnoseal TEC-21 is supplied as a zinc sacrificial anode for compatible marine corrosion protection applications.

Teardrop Plate Design
The Tecnoseal TEC-21 features a teardrop profile with a rounded end and a tapered opposite end. Its two recessed mounting holes are arranged along the plate's longitudinal axis.
The mounting holes measure 8.5 mm in diameter, with a centre-to-centre spacing of 41 mm. These dimensions should be verified against the existing anode before replacement.
Marine Corrosion Protection
The zinc material acts as a sacrificial element, helping reduce galvanic corrosion of associated metallic components when correctly installed with the required electrical contact.
The suitability of a zinc sacrificial anode depends on the operating water conditions and the existing cathodic protection system.
Inspection and Replacement
Sacrificial zinc anodes gradually lose material during service. Periodic inspection is recommended to assess their condition and determine when replacement is necessary.
Before ordering, verify the 136 × 58 × 14 mm body dimensions, 41 mm mounting hole spacing and 8.5 mm hole diameter against the original anode.
Supply: One Tecnoseal TEC-21 zinc teardrop sacrificial plate anode.
