Main description

The CORTECO 20026342 FPM B1BASLRSX2 100x125x13 rotary shaft seal is a high-performance oil seal ring designed for reliable rotary sealing of crankshafts and other critical rotating components. Manufactured from advanced FPM (fluor elastomer), this seal offers outstanding resistance to oils, fuels, greases and high operating temperatures, ensuring long service life in demanding automotive and industrial environments.

The B1BASLRSX2 configuration represents a double lip oil seal with an integrated dust lip. The primary sealing lip ensures effective retention of lubricants at the crankshaft interface, while the secondary dust lip protects the sealing area from dirt, moisture and abrasive particles. Compared to a single lip seal, this design significantly improves sealing reliability and reduces the risk of premature failure in harsh operating conditions.

With dimensions 100x125x13, this rotary shaft seal is commonly used in engine assemblies, crankshaft housings and drive systems where stable technical sealing is essential. The FPM material maintains elasticity and sealing efficiency even under prolonged exposure to elevated temperatures and aggressive media, making it particularly suitable for modern engines and high-load applications.

This seal is compatible with selected OEM applications from BMW and Land Rover, covering multiple crankshaft sealing references used in professional service and maintenance. As a product of CORTECO, it meets strict quality standards expected by B2B customers in automotive, industrial and machinery sectors.

The combination of FPM fluor elastomer and double lip construction ensures high durability, thermal stability and consistent sealing performance, even under continuous operation and dynamic load conditions.
