Tecnoseal R3 Rudder Anode Zinc 3-3/4" Diameter

The Tecnoseal R3 is a zinc rudder anode designed to provide galvanic corrosion protection for rudder assemblies in saltwater and brackish water environments. This full-size anode features a 3-3/4" (3.63") outer diameter and measures 0.52" in height, offering substantial protection for marine rudder systems.

Key Specifications:

• Material: Zinc alloy for superior galvanic protection
• Outer Diameter: 3.63 inches
• Height: 0.52 inches
• Weight: 1.56 lbs
• Includes stainless steel hex nut and socket cap screw
• Features captive hex nut design for easier underwater installation

The R3 rudder anode comes complete with all necessary hardware for installation, including a corrosion-resistant stainless steel hex nut and socket cap screw. The captive hex nut design is particularly beneficial for underwater installations, allowing for easier service and replacement without the need to access both sides of the mounting point. Zinc anodes are recommended for saltwater and brackish water applications where they provide the most effective protection against galvanic corrosion.
