CORTECO 12013424 FPM 35x72x10 BA Rotary Shaft Seal

Applications - Engine and Industrial Shaft Sealing

The CORTECO 12013424 FPM 35x72x10 BA rotary shaft seal is designed for reliable shaft sealing in automotive engines, gearboxes, pumps, and industrial drive systems. With dimensions 35x72x10 mm, it ensures effective oil retention and protection against contamination in rotating assemblies.

This oil seal is commonly installed in systems operating with lubricating oils and grease, where secure rotary sealing is essential to maintain mechanical integrity and prevent leakage.

Advantages - FPM Material and BA Construction

Manufactured by CORTECO, a globally recognized seal manufacturer, this model is produced from high-performance FPM FKM material. Compared to standard NBR compounds, FPM provides superior resistance to oils and grease, elevated temperatures, and chemical exposure, making it suitable for demanding environments.

The BA design indicates a single lip oil seal with a metal case and a spring-loaded sealing lip. The integrated garter spring maintains consistent radial pressure on the shaft, ensuring stable sealing performance and extended service life. This configuration is ideal for applications where a double lip oil seal is not required but high durability remains essential.
