NIPPON PISTON RING CO., LTD. was established in Japan in 1934. NPR products are used in all kind of engines with high quality backed up by proven technology and abundant lineup. A piston ring must have both spring-like tension and the properties to become a true circle when closed. In the combustion chamber of engine, NPR’s piston rings serve to seal combustion gas, control lubricating oil, dissipate heat, and prevent wear and seizure under the severe conditions of operation. Now that engines are required to be more compact, lighter, and more sophisticated in performance, the choice of piston ring materials has been widened to include steel in addition to the traditional cast iron. Moreover, in order to enhance their wear resistance and durability, they also undergo various surface treatments including nitriding and PVD treatment.
