Tecnoseal Pair Of Disc Rudder Anode - Zinc - 90mm

Tecnoseal 00102E zinc pair-type rudder and trim-tab anodes form a matched 90mm two-disc set for through-bolt installation on opposite sides of a suitable rudder, trim tab or underwater plate. The zinc castings are supplied as a pair with fastening hardware.

What Is This Pair of Disc Anodes Used For?

One anode half is fitted on each side of the protected component, with the central fastening passing through the assembly. When the metal faces and fastening path provide the intended electrical continuity, the zinc is consumed in preference to the connected underwater metal.

Key Features

• Brand: Tecnoseal
• Part number: 00102E
• Product category: Pair-type disc rudder / trim-tab anode
• Alloy: Zinc
• Nominal outside diameter: 90mm
• Supply: Two matching anode halves with fastening hardware
• Typical water-selection guide: Salt water
• Application: Suitable rudders, trim tabs and underwater plates with matching fixing geometry

How Do I Confirm Fit?

Confirm the outside diameter, centre fixing-hole diameter, centre-boss depth and available clearance on both sides of the component. This product should not be selected by diameter alone, because the fastening and centre geometry must also match the existing installation.

Which Anode Alloy Should I Choose?

• Zinc: a conventional choice for salt-water operation.

Use the alloy specified by the vessel, drive or equipment manufacturer and keep the choice consistent with the existing cathodic-protection system. Water salinity, connected metals and stray-current conditions can change the correct selection.

Installation and Maintenance

Remove the old anode and clean the rudder or trim-tab mounting faces and electrical contact points to bare metal. Fit the replacement using serviceable fasteners and the equipment manufacturer’s tightening procedure. Do not paint the anode or its electrical contact surfaces.

Inspect the anode during scheduled servicing. Replace it when substantially consumed, damaged or loose, and check bonding continuity or possible stray-current faults where consumption is unusually fast or uneven.

Alloy Standards and Manufacture

Tecnoseal sacrificial anodes are manufactured in Grosseto, Tuscany. Alloy batches are checked using spectrometric analysis and produced to the applicable current US-MIL alloy specifications used by Tecnoseal for zinc, aluminium and magnesium marine anodes.

Frequently Asked Questions

• Is this one disc or a pair? It is a two-disc set intended for opposite sides of the protected component.
• Can I fit only one half? Use the complete matched arrangement specified for the installation; fitting only one half changes the fixing and protection layout.
• Is it suitable for fresh water? Zinc is generally selected for salt water. For fresh water, confirm whether a dimensionally equivalent magnesium version is specified.
