Tecnoseal Cummins Brass Plugs for Marine Engine Pencil Anodes

Tecnoseal Cummins Brass Plugs for Marine Engine Pencil Anodes – BSPT & NPT

Tecnoseal Cummins brass plugs are replacement mounting fittings designed for sacrificial pencil anodes used in marine engine heat exchangers and cooling systems. These brass components provide the connection between a compatible zinc pencil anode and its installation point, allowing the mounting plug to be replaced separately from the anode.

The range includes four brass plugs with different external threads, internal connections and head dimensions. The 02043TP and 02044TP models feature 1/2" BSPT tapered external threads, while the 02045TP uses a 3/8" BSPT connection. The 02045-1TP is equipped with a 3/8" NPT tapered thread.

Internal connections include 3/8" UNC and 7/16" UNF threads, along with a 15.50 mm connection dimension on the 02043TP model. The plug head dimensions range from 11 to 22 mm, and individual weights range from 0.02 to 0.06 kg. All four versions are made from brass and supplied without sacrificial zinc anodes.

Model Selection

Select the correct Tecnoseal Cummins brass plug by matching the existing external thread, internal anode connection and head dimensions. Although the 02043TP and 02044TP share the same 1/2" BSPT external thread and 22 mm head dimension, their internal connections differ.

The 02045-1TP and 02045TP both feature 3/8" UNC internal connections but use different external threads and head dimensions. The 02045-1TP has a 3/8" NPT external connection and an 11 mm head, while the 02045TP features a 3/8" BSPT external connection and a 19 mm head.

BSPT and NPT tapered pipe threads should not be considered interchangeable solely because their nominal sizes match. Verify the existing fitting specifications before ordering.

Supply: All four models are supplied as individual brass mounting plugs without sacrificial anode rods.
