Main Description

The Rotary Shaft Seal CORTECO 12011833 FPM B1BASLRSX7 30x44x8 is a high-performance industrial sealing component developed for use in demanding automotive environments. Manufactured from FPM elastomer, the seal provides outstanding resistance to high temperatures, engine oils, fuels, and chemical aging, making it suitable for modern powertrain systems operating under continuous load.

The precisely formed sealing lip ensures stable and uniform contact with the shaft surface, effectively preventing oil leakage while minimizing wear. This design supports consistent sealing performance even under fluctuating speeds and thermal conditions. Compared to standard NBR rubber gaskets, FPM material offers significantly higher thermal stability and extended service life, reducing maintenance intervals and downtime.

With compact dimensions of 30x44x8, the seal is optimized for applications where installation space is limited and precision is critical. It functions as a dynamic sealing ring for rotating shafts and integrates seamlessly into engine housings and drivetrain assemblies. Standard installation methods can be used, provided proper axial alignment is maintained.

The shaft seal is compatible with OEM references used by Alfa Romeo, Fiat, and Lancia, including:
Alfa Romeo 60807290, 40005000
Fiat 7541733, 40005000, 40004320
Lancia 7541717, 40004320

Due to its consistent quality and predictable performance, the CORTECO 12011833 is widely selected by automotive service centers, parts distributors, and B2B customers seeking high-durability industrial seals for both automotive and related industrial applications.
