At RMS Marine Service, we understand the critical role piston rings play in marine engine efficiency and longevity. That’s why we supply high-performance Alu Coated Piston Rings, engineered for strength, durability, and optimal engine performance in the harshest maritime conditions.

With years of expertise in marine components, we offer only the finest products that meet strict industry standards. Our Alu Coated Piston Rings are the perfect solution for operators seeking reduced wear, enhanced sealing, and longer engine life.

What is an Alu Coated Piston Ring?
An Alu Coated Piston Ring is a piston ring coated with an advanced aluminum-based material using thermal spraying or other precise application techniques. The result is a hard, smooth, and corrosion-resistant surface, ideal for use in high-pressure marine environments.

Aluminum coatings offer exceptional thermal conductivity, low friction, and strong corrosion resistance—qualities that help marine engines operate efficiently even under extreme conditions.

• Friction Reduction: Minimizes friction between the piston ring and cylinder liner for better efficiency and reduced wear.
• Heat Dissipation: Enhances heat transfer to prevent piston damage caused by thermal expansion.
• Corrosion Protection: Creates a natural oxidation barrier that guards against saltwater-induced corrosion.
• Extended Durability: Reduces wear on the piston and liner, improving engine service life and performance.
