The CORTECO 12013361 FPM B1BASLRSX7 80x100x10 rotary shaft seal is engineered for reliable sealing of rotating shafts in engines and transmission systems. It is commonly used as a crankshaft seal and gearbox shaft seal, ensuring effective oil retention and protection against dust and contamination.

This oil seal is compatible with numerous OEM references across major brands, including CITROEN, DAF, IVECO, LADA, MAN, MERCEDES BENZ, NISSAN, PEUGEOT, RENAULT, RENAULT TRUCKS, SAF, VOLVO and ZF applications. Its wide cross reference coverage makes it a dependable replacement solution in both automotive and heavy duty sectors.

Advantages - FPM Material and B1BASLRSX7 Construction

Manufactured from FPM FKM (fluoroelastomer), this technical seal offers superior resistance to oils and grease, fuels, and elevated temperatures. Compared to standard NBR seals, FPM ensures higher thermal stability and longer service life in demanding operating environments.

The B1BASLRSX7 design includes a metal reinforced outer case, a spring loaded primary sealing lip, and an additional dust lip. This double lip oil seal configuration enhances sealing efficiency while protecting the shaft area from dirt and abrasive particles. The integrated garter spring maintains consistent radial pressure on the shaft, ensuring stable rotary sealing performance.
