National Oil Seal 711088 Differential Pinion Seal Multi-Lip

The National Oil Seal 711088 is a Differential Pinion Seal engineered to deliver reliable, leak-free performance in demanding drivetrain applications. Featuring a spring-loaded, multi-lip design, this seal ensures consistent contact with the pinion shaft, effectively retaining gear oil and blocking contaminants from entering the differential housing.

Key Features:

• Spring-Loaded Multi-Lip Design – Maintains consistent sealing pressure against the shaft for long-lasting performance
• Wide Temperature Range – Rated from -20°F to 300°F (-29°C to 149°C) for use in extreme operating conditions
• EP Lubricant Resistant – Specifically formulated to resist degradation from extreme-pressure (EP) gear lubricants used in differentials
• Low Swell in Hydrocarbon Fluids – Maintains dimensional stability when exposed to petroleum-based gear oils
• Premium National Quality – Manufactured to OE specifications for a precise, no-compromise fit

National has been a trusted name in sealing solutions for over 75 years, providing drivetrain components that meet or exceed original equipment standards. The 711088 differential pinion seal is a direct-fit replacement suitable for professional shop or DIY differential service.
