The SL66732 gasket is a PMA aircraft engine sealing gasket used in Continental-compatible piston engine assemblies. It is an OEM replacement alternative for 66732, used to provide a pressure- and oil-resistant seal between mating engine components such as housings or cover interfaces depending on engine configuration.

It is designed for use in high-vibration, high-temperature environments typical of aircraft piston engines, where reliable sealing is required to prevent oil leakage and maintain internal pressure integrity.

Key features include:

PMA replacement gasket (alternate to 66732)
Precision-cut sealing material (fiber/composite depending on revision)
Provides oil- and pressure-resistant sealing
Designed for engine housing / cover interface applications (IPC-dependent use)
Withstands vibration and thermal cycling in aviation engines
Compatible with Continental piston engine configurations
Used in engine assembly, maintenance, and overhaul procedures
Aviation-grade consumable sealing component
Ensures proper mating surface sealing under torque load
Commonly replaced during routine engine overhaul or teardown maintenance
