Tecnoseal R1AL 1.85 in Aluminum Rudder Anode

The Tecnoseal R1AL rudder anode is a aluminum sacrificial anode sized for direct protection of underwater rudder hardware. Its round body measures 1.85 in in outer diameter and 0.28 in high, giving the anode a defined contact footprint without adding unnecessary bulk around the rudder installation. The sacrificial metal is intended to corrode preferentially so more valuable submerged metal components are not the first parts attacked by galvanic corrosion.

This R1AL weighs 0.10 lb and includes a stainless steel hex nut and socket cap screw for installation. A captive hex nut is built into the assembly, a useful detail when the anode is being fitted underwater or in another location where loose hardware is difficult to manage. The full-size rudder format makes this a direct service item for routine corrosion-protection maintenance. Browse more marine anodes.
