O-RING (Nissan NICK238616)

A damaged retaining ring can allow assembled components to separate under load, leading to mechanical failure. The O-RING listed under catalog reference NICK238616 is an aftermarket replacement part cross-referenced to Nissan. This type of part functions as a circular seal that prevents fluid or gas leakage between mating surfaces. A plain mechanical function is to maintain compression against a groove wall to block passage. A concrete generic failure consequence is that a worn or cracked O-ring can cause gradual pressure loss in a sealed system. During routine service, a technician may find the O-ring hardened or brittle from heat exposure. Verify the serial number or application, then call (562) 693-7748.
