The chemical demands of various transmission and driveline fluids require a variety of seal materials. Federal-Mogul offers a complete portfolio that ranges from nitrile butadiene rubber (NBR) to low-temperature FKM, which is capable of maintaining flexibility to -40° C. We also have a full offering of base-resistant elastomers, including AFLAS^®, which is increasingly used in high-performance transmission units, where its unique properties help achieve sealed-for-life units.

Our transmission output seals combine a high-performance sealing lip with a unique booted design. This protects the yoke from undercarriage contamination and compensates for the large amount of shaft endplay that complicates the contamination issue.
