Tecnoseal Shaft Anode Zinc Shaft Anodes/Zincs

Tecnoseal zinc shaft anodes, also called propeller shaft zincs or collar anodes, are sacrificial anodes. They protect a boat's underwater running gear from galvanic corrosion. The anode is a collar that mounts around the propeller shaft. In the water, the zinc corrodes in place of the shaft and the nearby metal components.

Key Features:

• Zinc construction: Zinc is a sacrificial anode material commonly used in marine applications.
• Collar-style design: The anode fits around the shaft. It sits close to the metal it protects and leaves the rest of the underwater assembly unobstructed.
• Secure mounting: The anode is held in place with mounting holes and hardware.
• Range of shaft sizes: Tecnoseal makes the line in a range of inner diameters. Choose the size that matches your propeller shaft so the fit is snug.

Zinc anodes wear away as they work. Inspect them regularly and replace them once they are significantly eroded. This keeps the shaft and other underwater metals protected. Select the child item that matches your shaft diameter.
