The SL14260 oil seal is an aircraft engine elastomer sealing component used in Continental-compatible piston engines. It is typically installed at the tachometer drive shaft or accessory housing sealing interface, where it prevents engine oil leakage while allowing rotational movement of the drive shaft.

This seal is designed for continuous exposure to engine oil, heat, and vibration in aviation engine environments, and is commonly replaced during engine overhaul or accessory case maintenance.

It is also known as an alternate replacement for OEM part LW14260.

Key features include:

PMA replacement oil seal (tach drive / accessory interface)
Replaces OEM LW14260
High-temperature elastomer sealing lip design
Prevents engine oil leakage at rotating shaft interfaces
Designed for crankcase / accessory housing applications
Compatible with Continental piston engine configurations (model-dependent IPC use)
Resistant to aviation engine oils, heat, and vibration
Precision-molded rubber/metal bonded construction
Used in engine accessory drive and tachometer drive assemblies
Standard consumable part during engine overhaul and maintenance
