Piston Rings


Dover High Performance Plastics manufactures a range of piston rings for many high pressure applications. We design and manufacture high-quality piston rings that improve combustion efficiency and reduce oil consumption. Depending on the application, we can recommend the right product, for the project.

Our piston rings seal the combustion chamber so that here is no transfer of gases released into the crank. They also support heat transfer from the piston leading into the cylinder wall. When choosing a piston ring, measuring the end gap is crucial for a perfect fit and efficiency.
