The 652458 exhaust flange gasket is an OEM Continental sealing gasket used at the exhaust port interface between the cylinder exhaust outlet and the exhaust system flange. It is designed to create a high-temperature, gas-tight seal that prevents exhaust leakage while maintaining secure mechanical coupling between the cylinder head and exhaust pipe assembly.

This part supersedes 631544, providing an updated OEM specification for improved fit and durability in Continental aircraft piston engine exhaust systems.

Key features include:

Genuine Continental OEM exhaust flange gasket
High-temperature resistant metallic/graphite sealing construction (application dependent)
Designed for gas-tight sealing at exhaust port interface
Prevents exhaust leaks and heat damage to surrounding components
