Although often overlooked, piston rings play a fundamental role in sealing the combustion chamber and controlling oil consumption. Namura, known for its high-quality parts, delivers a product that will meet the demands of even the most discerning users. ### Advanced Material Technology Namura utilizes carefully selected materials and advanced technologies to ensure excellent performance and durability of its piston rings. The type of cylinder sleeve, its coating, engine size, and stroke type (2 or 4) – all these factors are considered when designing the rings to perfectly match them to the specific application. ### Compression Rings Namura NA-10012R compression rings are made of highly ductile cast iron or stainless steel alloy. Both materials offer exceptional wear resistance and provide a tight seal for the combustion chamber. Additionally, depending on the model, chrome, phosphate, or nitride coatings are applied, further enhancing their durability and resistance to extreme temperatures and pressures. ### Oil Control Rings Namura oil control rings consist of three components: two scraper rails made of highly ductile cast iron or stainless steel alloy, coated with chrome, nitride, or phosphate, and a single expander ring made of stainless steel. This design ensures effective scraping of excess oil, preventing it from entering the combustion chamber and minimizing oil consumption. ### Choose Namura Quality By choosing Namura NA-10012R 101.97mm piston rings, you are investing in the reliability and performance of your engine.
