Autopart International 1776-520376 Differential Pinion Seal

The Autopart International 1776-520376 is a precision-engineered differential pinion seal designed to prevent gear oil leakage at the pinion shaft of the differential assembly. This critical seal maintains proper lubrication within the differential housing while keeping contaminants out, ensuring reliable drivetrain performance and preventing costly fluid loss.

Key Features:

• Manufactured to meet or exceed OEM specifications for precise fit and reliable sealing
• Constructed from application-specific elastomer materials (nitrile, viton, or polyacrylate) engineered for the specific operating conditions
• Prevents differential fluid leaks at the pinion shaft entry point
• Designed to withstand the heat, pressure, and rotational demands of differential operation
• Direct replacement for worn or leaking original equipment seals

Autopart International differential pinion seals are manufactured in state-of-the-art facilities with rigorous quality control processes to ensure proper fitment, durability, and long-lasting performance. Regular inspection and replacement of pinion seals helps maintain differential integrity and prevents premature wear of internal components.
