Reliable Differential Seal for Audi and Volkswagen Vehicles

The Elring 228.490 differential seal is engineered to provide effective sealing performance for driveline components in select Audi and Volkswagen models. Designed with durable ACM (polyacrylate) material and a dust lip, this seal helps maintain optimal differential function by preventing fluid leaks and contamination.

• Constructed from ACM (polyacrylate) for enhanced chemical and temperature resistance
• Inside diameter: 48.0 mm, outside diameter: 60.0 mm, outer diameter 1: 74 mm
• Height of 26.5 mm ensures proper fit and sealing depth
• Includes a dust cover with dust lip to protect against debris ingress
• Radial shaft seal design type: SP with swirl type RD for improved sealing efficiency

Technical Details and Material Specifications

This differential seal features a robust ACM (polyacrylate) elastomer, known for its resistance to oils, heat, and aging, making it suitable for demanding automotive environments. The precise dimensions—48.0 mm inside diameter, 60.0 mm outside diameter, and 74 mm outer diameter 1—ensure compatibility with specific differential housings. The 26.5 mm height provides the correct sealing depth to maintain pressure and prevent leaks. The integrated dust lip offers additional protection by preventing dust and contaminants from entering the differential assembly. The radial shaft seal design (SP) combined with swirl type RD enhances the seal’s ability to maintain a tight barrier under rotational stress.
