The 648008P015 piston ring is an OEM Continental compression ring used in certified aircraft piston engines as part of a complete piston ring pack. It is designed to maintain combustion sealing inside the cylinder, regulate oil consumption, and support efficient heat transfer from piston to cylinder wall.

This ring is part of Continental’s standardized ring families used in multiple piston engine configurations, where correct selection depends on cylinder bore size, piston fit class, and overhaul manual specifications. It is commonly used in IO-520 / TSIO-series engine configurations depending on the specific build and cylinder arrangement.

Key features include:

Genuine Continental OEM piston compression ring
Precision-machined steel alloy construction for high thermal stability
Maintains combustion chamber sealing and stable compression
Controls oil film distribution to reduce oil consumption
