NOK 49442323 Differential Pinion Seal

The NOK 49442323 is a precision-engineered differential pinion seal designed to prevent lubricant leakage from the differential housing where the pinion shaft exits. This seal creates a critical barrier that keeps gear oil contained within the differential assembly while preventing contaminants from entering the system.

Key Features:

• Manufactured by NOK, a globally recognized leader in sealing technology
• Precision-molded construction ensures proper fitment and reliable sealing performance
• High-quality elastomer material resists heat, oil degradation, and wear
• Metal case provides structural integrity and proper press-fit installation
• Designed to withstand the rotational forces and operating temperatures of differential applications

This pinion seal is a critical maintenance component for preserving differential function and preventing costly fluid loss. Regular inspection and replacement of worn pinion seals helps maintain proper lubrication levels and protects internal gearing from damage.
