The YNF16888 SK100-1 arm cylinder seal kit is engineered for the hydraulic arm cylinder of the Kobelco SK100-1 excavator. As a widely used older-generation model, the SK100-1 is known for its reliability—but its hydraulic cylinders often require frequent seal replacement due to age, wear, and heavy digging applications. This kit restores sealing integrity, eliminates oil leakage, and ensures stable lifting and digging performance under demanding job-site conditions.
Built from premium PU, NBR, HNBR, and PTFE materials, each seal provides excellent resistance to pressure, heat, contamination, and hydraulic fluid degradation. The kit includes rod seals, piston seals, dust wipers, buffer rings, wear rings, and O-rings—ensuring a complete and reliable overhaul of the arm cylinder.
YNF Machinery ensures consistent stock availability, strong material quality, and competitive wholesale pricing, making it an ideal choice for global repair workshops, machine owners, and aftermarket parts distributors.
