The 648009P015 piston ring is an OEM Continental compression ring used in certified aircraft piston engines. It is part of the piston ring pack and is designed to seal combustion gases within the cylinder, control oil consumption, and assist in heat transfer from the piston to the cylinder wall. The “P015” suffix indicates a specific size/fit classification used during engine overhaul to match cylinder bore tolerances.

This ring is commonly used as part of Continental ring sets such as 649226 configurations, where multiple compression and oil control rings work together as a system. It is selected based on exact engine model, cylinder specification, and overhaul manual requirements. (turn0search12)
