Tecnoseal Martec Zinc Pencil Anodes with Brass Plugs

Tecnoseal Martec Zinc Pencil Anodes with Brass Plugs – 1/4" & 3/8" BSPT

Tecnoseal Martec zinc pencil anodes are complete sacrificial anode assemblies designed for compatible marine cooling systems and heat exchangers. Each model combines a cylindrical zinc anode with a brass mounting plug, providing a replaceable component that helps protect metallic cooling system parts against galvanic corrosion.

The range includes four models with zinc rod diameters of 10 and 12 mm and lengths from 15 to 40 mm. The Tecnoseal 02150T, 02151T and 02152T feature 1/4" BSPT tapered mounting threads, while the larger 02153T uses a 3/8" BSPT connection. All versions have a 17 mm brass plug head and use the 2T pencil configuration.

The zinc rod dimensions differ between models, allowing replacement according to the existing Martec installation. The 02150T measures 10 x 15 mm, the 02151T measures 10 x 26 mm, the 02152T measures 10 x 40 mm, and the 02153T measures 12 x 40 mm. Complete assembly weights range from 0.02 to 0.06 kg.

These Tecnoseal anodes correspond to Martec original part numbers 950-7300, 950-7301, 950-7302 and 950-7304. All four models are supplied complete with brass mounting plugs.

Model Selection

Select the correct Tecnoseal Martec pencil anode by matching the original Martec part number, zinc rod diameter, rod length and brass plug mounting thread.

The 02150T, 02151T and 02152T share a 10 mm zinc rod diameter and a 1/4" BSPT mounting connection, but have different rod lengths of 15, 26 and 40 mm respectively. The 02153T features a 12 x 40 mm zinc rod and requires a 3/8" BSPT connection.

Although all four models have 17 mm plug heads and the same 2T configuration, their mounting threads and zinc rod dimensions differ. Check the existing assembly before ordering.

Supply: Each model is supplied as one complete zinc pencil anode assembly with brass mounting plug.
