This gasket set provides the sealing elements for the hydraulic system of the host tractor. It sits between mating surfaces in the hydraulic circuit, preventing fluid bypass and maintaining system pressure. A failed gasket in this location allows oil to leak externally or internally, which reduces hydraulic power and can cause erratic implement response. The set includes all the sealing rings needed for a complete overhaul of the designated hydraulic assembly, matching the original profile to seat correctly in the machined grooves.
