Tecnoseal 130-4434 Onan Zinc Pencil Anode Ø13x26 mm with 3/8" BSPT Brass Plug

Tecnoseal 02031T / 130-4434 Onan Zinc Pencil Anode Ø13x26 mm with 3/8" BSPT Brass Plug

The Tecnoseal 02031T is a complete zinc sacrificial pencil anode assembly designed for compatible Onan marine generator cooling systems and heat exchangers. It combines a cylindrical zinc anode with a brass mounting plug, providing corrosion protection for metallic components exposed to cooling water.

The zinc rod measures 13 mm (0.51 in) in diameter and 26 mm (1.02 in) in length. The brass mounting plug features a 3/8" BSPT (Gas Conico) tapered external thread and an 18 mm (0.71 in) head dimension, allowing installation into a compatible engine cooling system fitting.

Weighing 0.06 kg (0.13 lbs), the Tecnoseal 02031T uses the manufacturer's 2T pencil configuration and corresponds to Onan original part number 130-4434. The zinc anode and brass plug are supplied together, allowing replacement of the complete assembly during generator cooling system maintenance.

Technical Specifications

Component Configuration

The Tecnoseal 02031T combines a zinc pencil anode with a brass mounting plug into one complete replacement assembly. The corresponding components are also listed separately:

• Tecnoseal 02031: Zinc pencil anode only, Ø13 x 26 mm
• Tecnoseal 02031TP: Brass mounting plug with 3/8" BSPT external thread
• Tecnoseal 02031T: Complete zinc pencil anode with brass plug

Application and Compatibility

The Tecnoseal 02031T is listed as a replacement for Onan original part number 130-4434. It is designed for compatible marine generator cooling system installations requiring a zinc pencil anode with a 13 mm diameter, 26 mm rod length and 3/8" BSPT brass mounting plug.

• Onan marine generator cooling systems
• Compatible marine heat exchangers
• Replacement of complete sacrificial zinc anode assemblies
• Cooling system fittings requiring a 3/8" BSPT tapered mounting thread

Installation and Replacement

Before ordering, verify the original Onan part number and compare the existing anode assembly with the Tecnoseal 02031T dimensions. The zinc rod measures 13 mm in diameter and 26 mm in length, while the brass plug features a 3/8" BSPT tapered thread and an 18 mm head.

The sacrificial zinc element should be inspected periodically and replaced when sufficiently consumed by corrosion. The Tecnoseal 02031T includes both the zinc rod and brass mounting plug for replacement as a complete assembly.

Supply: One zinc pencil anode complete with brass mounting plug.
