NOK 49442387 Pinion Seal

The NOK 49442387 is a precision-engineered pinion seal designed to prevent lubricant leakage from differential and axle assemblies. This seal creates a reliable barrier between the rotating pinion shaft and the differential housing, protecting internal components from contamination while retaining gear oil.

Key Features:

• Manufactured by NOK, a leading global supplier of oil seals and automotive sealing solutions
• Precision-molded design ensures proper fit and sealing performance
• High-quality elastomer construction resists heat, oil, and chemical degradation
• Metal case provides structural rigidity and press-fit installation
• Garter spring maintains consistent sealing lip pressure against the pinion shaft

Pinion seals are critical maintenance components that should be replaced whenever differential work is performed or when leakage is detected. NOK seals are trusted by professional technicians and OE manufacturers for their durability and reliability in demanding drivetrain applications.
