The 654719P005 piston ring is a Continental OEM compression ring used in aircraft piston engine assemblies. It is part of the piston ring set installed on the piston to maintain compression, control oil consumption, and regulate heat transfer between the piston and cylinder wall. This specific ring variant is identified as a “#2 compression ring” in Continental piston configurations and is used in approved Continental engine models depending on cylinder/piston group compatibility.

Key features include:

Genuine Continental OEM piston compression ring
Precision-machined steel alloy construction
Designed for sealing combustion gases in the cylinder chamber
Helps regulate engine oil film on cylinder walls
Optimized for high-temperature aviation piston operation
Wear-resistant surface treatment for extended service life
Part of multi-ring piston sealing system (#1 / #2 / oil control ring stack)
Supports efficient compression and combustion stability in certified engines
FAA-approved component for Continental piston engine overhauls
Used in various Continental piston engine families depending on IPC configuration (application-specific)
