Piston Rings

Piston rings for aerospace reciprocating engines, encompassing compression, oil-control and scraper ring variants manufactured from cast iron, ductile iron, steel and advanced coatings such as PVD chromium nitride or thermal-sprayed molybdenum, with precision honing, lapping and surface finishing processes employed to achieve the tight dimensional tolerances and gas-sealing performance required by piston-engine certification standards.
