The 654555 Oil Cooler Gasket is an OEM sealing gasket used in Continental aircraft piston engine oil cooler assemblies. It is installed between the oil cooler and engine adapter surface to ensure a proper oil-tight seal, preventing leakage while maintaining correct oil pressure and flow through the engine’s cooling circuit. It is commonly used in Continental front-mount and rear-mount oil cooler configurations depending on engine model.

This gasket is designed to withstand high oil temperatures and continuous pressure cycles typical of aviation piston engines, ensuring reliable sealing performance in certified engine systems.

Key features include:

Genuine Continental OEM oil cooler gasket
Precision die-cut sealing interface for oil cooler mounting
High-temperature and oil-resistant material construction
Ensures leak-free oil circulation through cooler system
Designed for aviation piston engine oil cooling circuits
Compatible with multiple Continental engine configurations (application-dependent IPC) 
Maintains stable oil pressure and thermal efficiency
FAA-approved aircraft engine sealing component
Used during oil cooler installation, replacement, and engine overhaul procedures
