YNF18301 / 707-98-47720 Bucket Cylinder Seal Kit is designed for Komatsu PC220-8 excavator bucket cylinder repair. When the bucket cylinder starts leaking oil, losing pressure, or moving weakly, a reliable seal kit is the fastest way to restore performance and reduce downtime. This kit is built for excavator hydraulic cylinder maintenance, helping reduce internal leakage, improve sealing performance, and support stable bucket movement under demanding jobsite conditions.

Stop Oil Leakage and Restore Bucket Cylinder Performance

It is suitable for replacing aged, hardened, cracked, or worn seals in the hydraulic cylinder, helping the machine recover smooth movement and dependable sealing performance.
