Elring 268.420 Differential Seal

Elring 268.420 Differential Seal

Elring 268.420 is a differential seal built for driveline and axle sealing applications where precise shaft sealing matters. Made from ACM (polyacrylate), it uses an A/BS radial shaft seal design with a dust lip to help manage contamination at the sealing edge.

This seal measures 37.0 mm inside diameter, 61.0 mm outside diameter, and 10 mm height, with a second listed height of 14 mm. It is a direct-fit sealing component for differential service where the original seal has hardened, worn, or begun leaking.

Key Features

• Elring part number 268.420
• ACM (polyacrylate) sealing material for driveline use
• Radial shaft seal design: A/BS
• Dust cover with dust lip for added sealing protection
• Inside diameter: 37.0 mm
• Outside diameter: 61.0 mm
• Height: 10 mm; secondary height listed at 14 mm
• Swirl type: RD

Detailed Description

Elring 268.420 is a differential seal intended for axle and driveline sealing service where the seal must retain lubricant and help keep road debris out of the housing. The ACM construction is suited to sealing applications that require stable performance in driveline environments, while the dust lip adds an extra barrier at the shaft interface. If you are replacing a leaking differential seal on a Mercedes-Benz, Honda Civic, or other vehicle using this OE-style size and profile, this part number 268.420 provides the dimensional match needed for service work.

This part cross-references Mercedes-Benz 020 997 19 47 and 023 997 90 47 for the same application.

What It Helps Fix

• Differential fluid seepage at the shaft seal area
• Contamination entering the axle or differential housing
• Noise or wear caused by low lubricant level from a leaking seal
• Seal hardening, cracking, or lip wear from age and heat
• Service replacement during driveline or axle maintenance

Installation Notes and Tips

Verify the shaft diameter, housing bore, and seal height before installation. Clean the sealing surface thoroughly and inspect the shaft for grooves or corrosion that can shorten seal life. Use proper installation tools to seat the seal evenly and avoid damaging the dust lip or sealing edge. Confirm the replacement matches the original radial shaft seal design and dimensions before assembly.

Quality Assurance

Elring is a recognized sealing-system manufacturer with OE-focused engineering for driveline and engine service parts. Elring 268.420 is built to the listed dimensions and material specification for accurate differential seal replacement.
