Automotive Piston Rings

automotive piston rings are split rings that fit into a groove on the outer diameter of a piston in a reciprocating engine, such as an internal combustion engine or steam engine. Automotive piston rings, that we offer, are made of wear-resistant materials, such as cast iron & steel, and are coated or treated to enhance the wear resistance. Two-stroke port design is critical to automotive piston rings’ life. Typically, top ring and oil control rings will be coated with chromium, or nitride, possibly plasma sprayed or have a pvd (physical vapor deposit) ceramic coating. main functions of automotive piston rings
