As a professional China wholesaler, we supply the Toyota 90311‑38020 High Quality Oil Seal, an OE‑matching replacement designed for Toyota Camry, Sienna, etc., with 3.0L 1MZ‑FE engines and automatic transmissions. It is the front oil pump seal located behind the torque converter in the bellhousing, preventing transmission oil leakage, maintaining lubrication pressure, and protecting internal components from dust and contamination.

Constructed with premium nitrile rubber (NBR) and a reinforced steel core, it withstands extreme temperatures (-40°C to 120°C), oil corrosion, and mechanical wear, ensuring long-lasting sealing performance. It features exact OE dimensions (38558.5 mm) and a precision‑molded lip design, enabling direct plug‑and‑play installation without modifications. We offer factory‑direct bulk supply with strict quality control: every seal undergoes pressure, leak, and durability testing to meet Toyota’s original standards, minimizing after‑sales issues for your business. It replaces OE numbers 90311‑38029 and 90311‑38129.
