Tecnoseal R1 Rudder Anode - Zinc - 1-7/8" Diameter

The Tecnoseal R1 Rudder Anode is an essential cathodic protection component designed for saltwater and brackish-water vessels. It plays a crucial role in preventing corrosion, which can compromise the integrity of your boat's rudder assembly and lead to costly repairs. If you spend significant time on the water, this anode is vital for maintaining your vessel's performance and safety.

Engineered from high-purity zinc, the Tecnoseal R1 Rudder Anode sacrifices itself electrochemically to protect your rudder shaft and hardware from galvanic corrosion. This process ensures that the anode corrodes preferentially to steel, stainless steel, and bronze components, thereby extending the life of critical steering components. With a diameter of 1-7/8 inches, it is designed to fit most standard rudder installations without interfering with steering performance.

Boat owners operating in coastal waters, estuaries, and offshore environments should inspect and replace their rudder anodes annually or every 12–18 months, depending on water conditions and salinity levels. The Tecnoseal R1 is compatible with conventional rudder post designs and is a straightforward bolt-on replacement that requires no special tools for installation.
