AGCO - 364776X1 - Massey Ferguson Hydraulic Valve O-Ring

This O-ring seals the connection between the hydraulic valve body and its mating port, preventing fluid leakage at the joint. It sits in the machined groove of the valve assembly, where it compresses against the opposing face to maintain a leak-free seal under system pressure. A worn or hardened O-ring allows external seepage or internal cross-port leakage, which reduces system pressure and causes erratic actuator response. This component matches the original groove dimensions and material specification, so it seats correctly without additional sealant or shimming.
