This gasket set provides the sealing rings for the hydraulic system socket on the host tractor. The set includes the multiple gaskets needed to seal the connection between the socket and the hydraulic line, preventing fluid leakage at the interface. A degraded seal in this location allows air ingress or fluid loss, which can cause erratic implement response or system cavitation. As an original-manufacturer component, the gaskets are formed to match the socket's groove geometry, ensuring the correct compression and sealing force when the fitting is torqued to specification.
