The materials used in manufacturing hydraulic seals are also vital to their performance. Common materials include rubber compounds, polyurethane, and PTFE (Polytetrafluoroethylene). Each material offers different advantages and is selected based on the operating environment. For example, PTFE seals are highly resistant to chemicals and extreme temperatures, making them ideal for demanding applications.

One of the key benefits of a wheel oil seal is its ability to reduce friction and heat generated during wheel rotation. By creating a tight seal around the axle, the seal minimizes the chances of oil leakage, which can lead to overheating and ultimately cause damage to the wheel assembly. This is particularly important for heavy-duty vehicles that endure long hours of operation and high levels of stress.

The design of PU oil seals also plays a significant role in their functionality
pu oil seal. They often feature a-like structure that creates a tight seal against the mating surface, preventing the leakage of oil or other fluids. This design, combined with the elastic memory of polyurethane, allows the seal to recover its original shape after compression, maintaining a consistent seal even under fluctuating pressures.
