The YNF16881 707-99-37180 boom seal kit is engineered for the boom hydraulic cylinder of Komatsu PC130-8 excavators. This kit helps restore the cylinder’s sealing performance, preventing oil leakage and maintaining stable lifting, digging, and holding functions. Manufactured with premium sealing materials—including NBR, HNBR, polyurethane, and PTFE—it withstands high operating pressures, temperature changes, and abrasive contaminants common in excavation environments.
The seal kit includes key components such as rod seals, piston seals, dust wipers, buffer seals, O-rings, and wear rings, ensuring complete restoration of the hydraulic cylinder.
