AGCO - 3907025M91 - Massey Ferguson Set of Sealing Rings

This set of sealing rings provides the gaskets needed to seal connections in the hydraulic system of the host tractor. The rings are placed at the interfaces between hydraulic lines, valves, and the pump or cylinder housings to prevent fluid leakage under operating pressure. A compromised seal allows oil to escape, which reduces system pressure and can introduce air into the circuit, leading to spongy actuator response and potential pump cavitation. As an original AGCO component, the rings are molded to the same cross-section and durometer as the factory-installed seals, ensuring they compress evenly in the groove without over-stressing the housing bore. On reinstallation, clean the mating surfaces thoroughly and confirm the rings seat fully before tightening the fittings.
