FAG SS2420 is a differential pinion seal built with a nitrile sealing material and a metal spring design with an auxiliary lip. It is engineered to help retain gear oil at the pinion area while keeping out dirt, dust, and moisture in demanding driveline service.

Key Features

• Part number SS2420 for differential pinion seal applications
• Nitrile sealing material for oil resistance in driveline use
• Metal spring construction with auxiliary lip for sealing support
• 2.374 in. bore diameter and 2.378 in. outside diameter
• 1.375 in. seal width for a precise fit in the housing
• Designed to help protect axle and differential components from contamination

Detailed Description

FAG SS2420 is a differential pinion seal specified for driveline and axle sealing applications where controlled lubricant retention matters. The seal’s nitrile material is paired with a metal spring and auxiliary lip to maintain contact at the sealing surface, while the 1.375-inch width, 2.374-inch bore diameter, and 2.378-inch outside diameter support accurate installation in the intended housing. For buyers searching differential pinion seal SS2420, FAG SS2420, or FAG differential seal replacement parts, this component is built around the dimensional and material requirements that matter in service.

This part cross-references Dorman - HELP 13739 for the same application.

What It Helps Address

• Gear oil seepage at the differential pinion area
• Contamination from dirt, dust, and moisture entering the seal area
• Wear related to loss of lubricant at the pinion seal
• Seal replacement needs on driveline and axle service jobs

Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation. Inspect the pinion shaft and housing surface for scoring or corrosion, since surface damage can affect sealing performance. Clean the sealing area thoroughly and confirm the seal is seated squarely during installation. For vehicle-specific searches such as differential pinion seal for Honda Civic or pinion seal replacement for Toyota Corolla, always match the dimensions and application details to the original part.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The seal construction is intended to support long-term protection of wheel end and driveline components from contamination and lubricant loss. Part number SS2420 is built to the listed dimensional and material specifications for the intended application.
