SEAL RING (Komatsu KO3EE-15-11930)

A damaged seal ring can allow fluid or gas to escape, reducing system pressure and causing operational inefficiency. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO3EE-15-11930. The seal ring functions as a static or dynamic barrier between two mating surfaces. Its primary mechanical role is to prevent leakage by compressing into a groove under assembly torque. A common failure consequence is gradual loss of containment, which may lead to component wear or contamination. Verify the serial number or application, then call (562) 693-7748. Keeping a seal ring in sound condition helps maintain consistent sealing force over the service interval.
