O-RING - METRIC (Komatsu KO3ED-38-12230)

KO3ED-38-12230: A damaged retaining ring can allow assembled components to separate under load, leading to mechanical failure. The Komatsu catalog reference KO3ED-38-12230 identifies this aftermarket replacement part as a metric O-ring. This type of part functions as a circular seal that prevents fluid or gas leakage between mating surfaces. A worn or missing O-ring may cause gradual pressure loss or contamination ingress in a sealed joint. During routine disassembly, an O-ring should be inspected for cracks or deformation that compromise its sealing ability. Keeping a retaining ring in sound condition helps maintain proper alignment and containment of adjacent parts. Verify the serial number or application, then call (562) 693-7748.
