Tecnoseal Nanni Diesel Zinc Pencil Anodes for Marine Engine Heat Exchangers

Tecnoseal Nanni Diesel Zinc Pencil Anodes for Marine Engine Heat Exchangers

Tecnoseal Nanni Diesel zinc pencil anodes are replacement sacrificial anodes designed for compatible marine engine heat exchangers and cooling-water systems. Their zinc bodies help protect metallic components against galvanic corrosion by providing a replaceable sacrificial element within the cooling circuit.

The range includes three models with body diameters of 10, 14 and 26 mm and lengths of 17, 26 and 25 mm respectively. Each version features a cylindrical zinc body with a projecting mounting section for installation into a compatible existing fitting.

The Tecnoseal 02100 measures 10 mm in diameter and 17 mm in length, with a 9 mm mounting extension and an 8 mm connection dimension. The 02101 features a 14 x 26 mm body, an 8 mm extension and a 10 mm connection dimension. The larger 02102 measures 26 x 25 mm, with a 10 mm extension and a 22 mm connection dimension.

All three anodes use the Tecnoseal T2 pencil configuration and are supplied individually without brass mounting plugs. Their weights range from 0.01 to 0.12 kg, depending on the model.

Available Models and Technical Specifications

Individual Model Specifications

Tecnoseal 02100 – Nanni Diesel Zinc Pencil Anode Ø10 x 17 mm

The Tecnoseal 02100 is a compact zinc pencil anode with a cylindrical body measuring 10 mm (0.39 in) in diameter and 17 mm (0.67 in) in length. Its projecting mounting section measures 9 mm (0.35 in) in length, with a connection dimension of 8 mm (0.31 in).

Weighing 0.01 kg (0.02 lbs), this anode uses the T2 configuration and is supplied separately without a brass plug. Its compact dimensions make it suitable for compatible Nanni Diesel engine cooling system fittings requiring this anode size.

• Product Code: 02100
• Material: Zinc
• Diameter (Ø): 10 mm (0.39 in)
• Body Length (l): 17 mm (0.67 in)
• Mounting Extension (l1): 9 mm (0.35 in)
• Connection Dimension (b): 8 mm (0.31 in)
• Weight: 0.01 kg (0.02 lbs)

Tecnoseal 02101 – Nanni Diesel Zinc Pencil Anode Ø14 x 26 mm

The Tecnoseal 02101 features a cylindrical zinc body measuring 14 mm (0.55 in) in diameter and 26 mm (1.02 in) in length. It has an 8 mm (0.31 in) mounting extension with a 10 mm (0.39 in) connection dimension.

The anode weighs 0.03 kg (0.07 lbs) and uses the T2 pencil configuration. Its different body and mounting dimensions provide an alternative replacement size for compatible Nanni Diesel marine engine cooling systems.

• Product Code: 02101
• Material: Zinc
• Diameter (Ø): 14 mm (0.55 in)
• Body Length (l): 26 mm (1.02 in)
• Mounting Extension (l1): 8 mm (0.31 in)
• Connection Dimension (b): 10 mm (0.39 in)
• Weight: 0.03 kg (0.07 lbs)
• Pencil Type: T2
• EAN: 8033837067610
• Supply: Zinc anode only

Tecnoseal 02102 – Nanni Diesel Zinc Pencil Anode Ø26 x 25 mm

The Tecnoseal 02102 is the largest zinc pencil anode in this Nanni Diesel selection, featuring a cylindrical body measuring 26 mm (1.02 in) in diameter and 25 mm (0.98 in) in length. Its projecting mounting section measures 10 mm (0.39 in), with a 22 mm (0.87 in) connection dimension.

Weighing 0.12 kg (0.26 lbs), the 02102 provides a larger sacrificial zinc body than the 02100 and 02101 models. It uses the T2 configuration and is supplied individually without a brass mounting plug.

• Product Code: 02102
• Material: Zinc
• Diameter (Ø): 26 mm (1.02 in)
• Body Length (l): 25 mm (0.98 in)
• Mounting Extension (l1): 10 mm (0.39 in)
• Connection Dimension (b): 22 mm (0.87 in)
• Weight: 0.12 kg (0.26 lbs)
• Pencil Type: T2
• EAN: 8033837067627
• Supply: Zinc anode only

Application and Compatibility

• Nanni Diesel marine engine cooling systems
• Compatible marine engine heat exchangers
• Replacement of sacrificial zinc pencil anodes
• Existing mounting fittings matching the specified dimensions

Model Selection

Choose the required Tecnoseal Nanni Diesel pencil anode by comparing the zinc body diameter, length and mounting connection dimensions with the existing component.

The 02100 is the smallest model, measuring 10 x 17 mm. The 02101 has a longer 14 x 26 mm body, while the 02102 features a wider 26 x 25 mm cylindrical body. Their mounting extensions and connection dimensions also differ, so the models should not be considered interchangeable based solely on their T2 configuration.

Confirm the existing anode dimensions and engine requirements before ordering.

Supply: All three models are supplied as individual zinc sacrificial anodes without brass mounting plugs.
