Trailer hub oil seals play a critical role in maintaining the integrity of the wheel hub assembly on trailers and other towed vehicles. These seals are designed to prevent the leakage of lubricating oil and the ingress of contaminants, ensuring the proper functioning and longevity of the wheel bearings and other internal components. The trailer hub oil seal is typically positioned within the hub assembly, creating a barrier that helps retain the lubricant and protect the bearings from moisture, dirt, and debris.

Leather oil seals are commonly used for parts that are exposed to dirt and poor lubrication. The major advantage of this material is that it can function in cases where synthetic rubber cannot function. They are used for shafts that have rough surfaces that are more than what rubber seals can handle. This is because they are pre-lubricated and have the capacity to absorb liquids.
