This O-ring serves as a flange seal at hydraulic and fluid connection points, appearing across O-ring kits and O-ring sets on a wide range of Wacker Neuson machines, including roller O-ring sets for models such as the RD7A, RD7H, RD7He, RD7Ye, RD12A-90, RTK82-SC3, RTKx-SC3, RTL82-SC3, and RTLx-SC3, as well as service kits for generators, hydronic heaters, skid steer loaders, track loaders, and utility track loaders. The "-8" designation in the official part name indicates the dash-8 size specification for this O-ring, which governs its outer diameter, inner diameter, and cross-section to ensure a precise fit at the flange sealing point.
O-rings at flange connections prevent fluid leakage between mating hydraulic or fluid circuit components. On the roller models listed, the hydraulic circuit operates at pressures up to 3200 PSI at the exciter relief valve and 4000 PSI at the exciter circuit relief valve, making a correctly sized and properly seated flange seal O-ring important for maintaining leak-free connections at those joints. Replacing O-rings during seal kit service intervals is standard practice when rebuilding hydraulic assemblies on these machines.
