Okada UB11A Hydraulic Breaker Seal Kit

This seal kit is designed for the Okada UB11A hydraulic breaker hammer. It contains all necessary seals for the cylinder, piston, and valve assemblies to restore hydraulic integrity and prevent oil leakage. The kit utilizes high-grade polyurethane (PU), polytetrafluoroethylene (PTFE), fluorocarbon (FKM), and nitrile rubber (NBR) materials suitable for extreme operating conditions. The components are engineered to withstand operating pressures up to 125 MPa and temperatures ranging from -35°C to 135°C. This kit fits the Okada UB11A breaker model commonly mounted on mini excavators from brands such as Kubota, Caterpillar, Hitachi, Komatsu, and John Deere. It serves as a direct replacement for OEM seal kits during routine maintenance or overhaul.
