U-SEAL (Nissan NI58621-2G000)

A worn U-seal can allow fluid leakage, reducing system pressure and causing erratic operation. This aftermarket replacement part references Nissan as the OE maker and cross-references part number NI58621-2G000. The U-seal functions as a static or dynamic seal, preventing fluid bypass between mating surfaces. A common failure consequence is gradual loss of sealing integrity, leading to contamination ingress or fluid loss. During operation, the seal's lip maintains contact under pressure to block leakage paths. The item ships at approximately 0.01 pounds. Verify the serial number or application, then call (562) 693-7748.
