SEAL - UCUP (Nissan NI23238-50081)

NI23238-50081: A worn u-cup seal can allow fluid bypass, reducing system pressure and causing sluggish operation. This aftermarket replacement seal references Nissan part number NI23238-50081. The u-cup seal is a lip-type sealing element that prevents leakage along a reciprocating rod or piston. Its flexible lips maintain contact under pressure, but hardening or cracking leads to external drips or internal cross-port leakage. In a typical cylinder application, a failed u-cup results in loss of holding force and increased cycle time. Verify the serial number or application, then call (562) 693-7748.
