This hydraulic flat gasket seals a connection point within the tractor's hydraulic system, preventing fluid leaks between mating surfaces. It sits between a port or fitting and its housing, maintaining system pressure and preventing contamination ingress. A degraded gasket allows external leakage, which reduces available hydraulic flow and can introduce air into the circuit. This original AGCO gasket is manufactured to the same material specification and thickness as the factory-installed seal, ensuring it compresses to the correct height for a leak-free joint without over-stressing the hardware. On reinstallation, clean both sealing surfaces and tighten the retaining hardware to the specified torque.
