Applications of the CORTECO 12001675 Rotary Shaft Seal

The CORTECO 12001675 rotary shaft seal is a high-quality oil seal designed for reliable rotary sealing of shafts in agricultural machinery, industrial equipment, and selected automotive applications. With dimensions 25x42x6/6.5, this shaft sealing ring is commonly used in gearboxes, drivetrains, pumps and mechanical assemblies where effective oil retention and protection against contamination are essential.

This seal is widely recognized as a replacement for OEM number Case IH 3402987R1, making it a proven solution for agricultural service centers, machine maintenance operations and B2B customers focused on long-term operational reliability. Its precise fit ensures stable sealing performance and reduces the risk of premature leakage.

BABSL Double Lip Design and NBR Material Advantages

The BABSL profile identifies this product as a double lip oil seal equipped with an additional dust lip. The primary sealing lip retains oil within the system, while the secondary dust lip protects the sealing area from dirt, dust, mud and other external contaminants. This design significantly increases service life and protects the shaft surface from accelerated wear.

Manufactured from NBR (nitrile rubber), the CORTECO 12001675 offers excellent resistance to oils and grease, fuels and typical operating media used in agricultural and industrial machinery. NBR provides a balanced combination of elasticity, abrasion resistance and dimensional stability, ensuring high durability and consistent sealing performance during continuous operation.
