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.
