Product Introduction:

03C 103 170 crankshaft rear oil seal is a core sealing component designed for 16V/1.6L engines. It is located at the end of the engine crankshaft and effectively prevents oil leakage and contaminants from invading, ensuring efficient operation of the engine. This product strictly follows the original factory standards and is compatible with mainstream brands such as Volkswagen and Skoda. It is the preferred solution for maintenance and parts replacement.

✅ High-end fluororubber material
Adopting high temperature resistant and anti-aging fluororubber (FKM), it can maintain elasticity in extreme environments of -30℃ to 250℃, resist oil, fuel and chemical corrosion, and eliminate leakage risks.

✅ Precision structural design
Laser engraving technology ensures accurate dimensions (inner diameter/outer diameter/thickness strictly matches the original parameters), and the double sealing lip fits the crankshaft tightly, maintaining stable performance under dynamic pressure.

✅ Ultra-long service life
Through 300,000 km endurance test, the wear-resistant coating reduces crankshaft friction loss, and the life of ordinary oil seals is increased by more than 50%, reducing the cost of frequent replacement.

✅ Ready-to-install adaptability
Pre-installed anti-deformation positioning ring, supports non-destructive installation, and is suitable for Volkswagen EA111 series engines (such as Polo 1.6L, Octavia 1.6L, Fabia 1.6L and other models), saving 50% of working hours.
