O-RING (Mitsubishi MB0556390016)

MB0556390016: A damaged retaining ring can allow assembled components to separate unexpectedly. The O-ring type seal is a circular elastomeric element that prevents fluid or gas leakage between mating surfaces. A worn or missing retaining ring may cause the O-ring to dislodge, leading to a sudden loss of sealing pressure. This aftermarket replacement part references Mitsubishi as the OE maker and carries the cross-reference number MB0556390016. During service, a retaining ring that fails to hold the O-ring in place can result in contamination entering the sealed area. Verify the serial number or application, then call (562) 693-7748.
