An additional dust protection lip provides enhanced protection against external contamination, contributing directly to high durability and consistent sealing performance. The left-hand thread design supports effective oil return during shaft rotation, improving overall sealing efficiency.

With dimensions of 85x154/160x9.5 mm, this single-lip oil seal is precisely matched to its intended application. It is suitable for use as a gearbox oil seal, engine oil seal, or rotary shaft sealing solution in systems requiring reliable technical sealing under demanding operating conditions.

The CORTECO 20037036 oil seal is widely selected by professional workshops, automotive service centers, and industrial maintenance teams seeking a dependable technical sealing solution for long-term operation.
