SEAL KIT - HYDRAULIC CYLINDER (Komatsu KO8769120)

KO8769120: A damaged hydraulic cylinder seal kit can cause fluid leaks and reduced system pressure. During operation, the seals inside a cylinder prevent pressurized fluid from bypassing the piston. Keeping these seals in sound condition helps maintain consistent force output and cycle timing. This aftermarket replacement part references the Komatsu catalog and carries the part number KO8769120. The kit includes multiple sealing elements that separate fluid chambers within the cylinder. A worn seal may allow internal leakage, leading to sluggish movement or inability to hold a load. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.03 pounds.
