U-SEAL (Nissan NI97103-35431)

A damaged U-seal can allow fluid leakage, leading to pressure loss in the system. During inspection, a worn U-seal may show cracking or deformation on its sealing lip. The U-seal functions as a dynamic sealing component that prevents fluid bypass between moving surfaces. Keeping a U-seal in sound condition helps maintain consistent system pressure and reduces the risk of contamination ingress. This aftermarket replacement part references Nissan catalog number NI97103-35431. The seal type relies on its lip geometry to create a positive seal under operating pressure.
