This seal ring set is a gasket assembly for the three-point hitch linkage of agricultural tractors. It seals the connection points in the hitch system, preventing fluid leaks and maintaining hydraulic pressure to the lift arms. A worn or damaged seal set causes slow or incomplete implement lift and can allow contamination into the hydraulic circuit. This original AGCO part is manufactured to the same interface dimensions as the factory assembly, so it seats correctly in the linkage bores without modification. On installation, clean the mating surfaces and ensure the rings are fully seated before pressurizing the system.
