85x135x8/19.5mm Differential Oil Seal, NBR Black

This brand‑new aftermarket 85x135x8/19.5mm TC‑type differential oil seal is made of black NBR rubber and reinforced metal shell for stable press‑fit installation on automotive differential assembly.

Double‑lip structure with garter spring maintains stable radial pressure on rotating shaft. It retains differential gear‑oil inside housing and stops dust, mud and splash‑water invading gear assembly. Suitable for auto repair shops, auto‑parts wholesalers and overseas bulk procurement.

Core functions

• Gear‑oil retention: Prevent differential gear‑oil leakage under driving vibration and shock load
• Dust & mud exclusion: Resist sand, mud and splash‑water contamination for various road conditions
• Reinforced metal shell: Anti‑rust and reliable interference fit for differential housing bore
• Garter‑spring pre‑load: Consistent sealing performance under frequent vibration and temperature fluctuation
