O-RING (Nissan NI11072-Z5501)

NI11072-Z5501: A damaged retaining ring can allow assembled components to separate under load, leading to mechanical failure. The Nissan catalog reference NI11072-Z5501 identifies this aftermarket replacement O-ring. An O-ring functions as a static seal by compressing between two mating surfaces to prevent fluid or gas leakage. Over time, an O-ring may harden or crack, causing gradual seepage that reduces system pressure. During disassembly, a technician might find the O-ring flattened or brittle, indicating replacement is needed. Keeping a sealing ring in sound condition helps maintain consistent containment in joined parts. Verify the serial number or application, then call (562) 693-7748.
