Tecnoseal R1AL Rudder Anode - Aluminum - 1-7/8" Diameter

The Tecnoseal R1AL Rudder Anode is a sacrificial aluminum protection system designed for marine vessels with exposed rudder assemblies. This 1-7/8" diameter anode prevents galvanic corrosion by corroding preferentially to the steel rudder shaft and components, extending the operational life of critical steering hardware. Marine professionals and boat owners rely on quality rudder anodes to protect against saltwater and brackish water corrosion damage that would otherwise compromise rudder integrity and steering reliability.

Constructed from high-purity aluminum, the Tecnoseal R1AL features a compact 1.85" outer diameter and 0.28" height profile that fits standard rudder post applications without obstruction. The anode includes a stainless steel hex nut and socket cap screw for secure fastening, with a captive design that simplifies installation and prevents hardware loss during underwater mounting. Aluminum anodes provide reliable galvanic protection in both saltwater and freshwater environments, with predictable consumption rates that allow for scheduled maintenance intervals and cost-effective replacement cycles.

This rudder anode suits cruising sailboats, powerboats, and commercial fishing vessels where steering system durability is critical to safety and performance. Installation requires no special tools—the hex nut and socket cap screw assembly allows rapid mounting to existing rudder post hardware. Regular inspection and replacement when anode thickness diminishes ensures continuous corrosion protection and prevents costly rudder damage that could compromise vessel maneuverability or require dry-dock repairs.
