Tecnoseal Renault Marine Zinc Engine Plug Anode Ø11 × 33 mm M16 × 1.5 – Osculati 43.562.00

Tecnoseal 02090-2T Renault Marine Zinc Engine Plug Anode Ø11 × 33 mm M16 × 1.5 – Osculati 43.562.00

The Tecnoseal 02090-2T is a zinc sacrificial plug anode designed for compatible Renault Marine engine cooling systems. Cross-referenced with Osculati 43.562.00, this threaded anode provides a replaceable sacrificial element intended to help protect internal metallic cooling-system components against galvanic corrosion.

The anode features a cylindrical zinc element measuring 11 mm in diameter and 33 mm in length, together with an M16 × 1.5 threaded connection and a 17 mm hex head width. These specifications are important when matching the replacement anode to the existing engine cooling-system port.

When correctly installed with suitable electrical contact and exposed to an appropriate cooling-water environment, the zinc material corrodes preferentially, helping reduce galvanic corrosion of electrically connected metallic components.

Technical Specifications

Renault Marine Engine Application

The Tecnoseal 02090-2T is intended for compatible Renault Marine engine cooling-system installations that use a threaded sacrificial zinc plug anode.

Such anodes are used to provide corrosion protection for metallic components in water-cooled marine engine systems. The exact mounting location depends on the engine design and may involve cooling passages or heat exchanger arrangements.

The available product information does not identify specific Renault Marine engine models. Compatibility should therefore be established by checking the existing anode and the engine manufacturer's parts documentation.

Construction and Mounting Dimensions

The Tecnoseal 02090-2T combines a cylindrical sacrificial zinc element with a threaded plug connection. Its specified dimensions are:

• Zinc element diameter: Ø11 mm.
• Zinc element length: 33 mm.
• Mounting thread: M16 × 1.5.
• Hex head width: 17 mm.

The M16 × 1.5 thread must correspond to the original engine anode port. The 11 mm diameter and 33 mm length of the zinc element should also be checked to confirm adequate clearance within the intended installation.

Zinc Sacrificial Corrosion Protection

Zinc is commonly used as a sacrificial anode material in saltwater marine corrosion protection systems. When correctly installed with electrical continuity to the protected metallic components, the zinc is consumed preferentially, helping reduce galvanic corrosion.

In compatible marine engine cooling systems, the replaceable zinc element provides a sacrificial component exposed to the circulating cooling water.

Selection of the appropriate anode material should follow the engine manufacturer's recommendations and the vessel's operating water conditions.

Inspection and Replacement

Inspect the zinc plug anode during routine marine engine cooling-system maintenance. Replace it when the zinc element becomes significantly depleted, damaged or otherwise unsuitable for continued service.

Before removing or installing the anode, follow the engine manufacturer's safety and maintenance procedures. Confirm the condition of the threaded connection and use the specified replacement dimensions.
