WJB WS711080 Differential Pinion Seal

The WJB WS711080 is a new differential pinion seal engineered to prevent gear oil leaks at the pinion shaft and protect drivetrain components from contamination. This seal serves as a direct replacement for National seal part number 711080 and is manufactured to meet or exceed OEM specifications.

Key Features:

• Flanged design for easier, more secure installation and precise seating
• Exterior ridges provide a secure, stable fit within the bore
• Machined rubber sealing surface delivers a consistent, leak-proof barrier that retains gear oil and repels water
• Secondary dust lip blocks dirt, debris, and contaminants from entering the differential assembly
• Wide temperature and fluid compatibility ensures reliable performance across varied driving conditions
• 100% new construction — no remanufactured components

Replacing a worn or leaking pinion seal is essential to maintaining proper lubrication in the differential and preventing costly damage to the ring and pinion gears. The WS711080 is produced in ISO-certified facilities and backed by a 12-month manufacturer warranty covering defects in materials and workmanship.
