80x141x12/22mm Differential Pinion Shaft Oil Seal, NBR Brown, QINGTE 440 / 398 Truck Rear Axle Seal

This brand‑new 80x141x12/22mm TC‑type flange differential pinion shaft oil seal has an unverified OE reference. Confirm the OE reference against the original part before ordering. Constructed with brown NBR rubber and reinforced metal flange shell for stable press‑fit installation for heavy‑duty truck differential pinion shaft assembly.

Double‑lip structure with garter spring maintains consistent radial pressure against rotating pinion shaft. It effectively retains differential gear oil inside housing and stops dust, mud and splash‑water invading differential assembly. Manufactured as aftermarket replacement part for QINGTE 440, QINGTE 398 series trucks. Suitable for auto‑parts wholesalers, repair workshops and overseas bulk procurement.
