Description
Product Overview
The Pro Marine Zinc Anode is a precision‑engineered sacrificial anode designed for demanding marine environments. Measuring 1/8 inch thick, 5‑1/8 inch outer diameter and 0.34 inch inner diameter, it fits a wide range of hulls, propeller shafts, and offshore fittings. Crafted from a premium blend of alloy steel, aluminum, iron, stainless steel and zinc, the anode is pressure‑die‑cast and then coated to resist the abrasive action of salt spray and seawater. The result is a robust, low‑maintenance component that continuously supplies electrons to protect surrounding metal structures from corrosion. Certified under ISO 9001, each unit undergoes strict quality checks to guarantee consistent performance and dimensional accuracy.

Usage
This anode is intended for ocean‑going vessels, offshore platforms, marina infrastructure, and any equipment constructed from iron, steel, aluminum, magnesium or similar metals that are exposed to saltwater. Install the anode on the submerged portion of a hull, propeller shaft, or structural member where it can act as a sacrificial element, gradually corroding in place of the protected metal. Its compact size makes it suitable for both new builds and retrofits, and the zinc alloy composition ensures a steady protective current even in low‑oxygen water conditions. Ideal for commercial shipping, fishing boats, pleasure craft, and coastal industrial installations.

FAQ
How does a zinc anode protect my vessel?
The zinc anode acts as a sacrificial metal, corroding preferentially to the hull or equipment. It releases electrons that neutralize the electrochemical reaction causing corrosion on the protected metal, effectively extending its lifespan.
Can I install this anode on an aluminum hull?
Yes. The zinc alloy is compatible with aluminum and provides effective cathodic protection, especially in seawater where aluminum is prone to pitting corrosion.
What maintenance is required?
Periodically inspect the anode for excessive wear or damage. Replace the anode when it has lost more than 30% of its original mass to maintain optimal protection.
Is the coating environmentally safe?
The coating is a marine‑grade epoxy that meets environmental regulations and does not leach harmful substances into the water.
Do you offer technical assistance for installation?
Our engineering support team can provide installation diagrams, torque specifications, and best‑practice recommendations to ensure correct placement and maximum effectiveness.
