O-ring for Komatsu HD4056

The O-ring 2810911141 functions as a circular cross-section seal, intended for installation within a groove where it is compressed between two surfaces to establish a seal. Its primary role is to contain fluids and prevent the entry of external contaminants in both static and dynamic applications. Within the Komatsu HD4056 mining truck, this component is utilized in various assemblies, including hydraulic cylinders, hose connections, pumps, and valves, where maintaining fluid containment under pressure is required for system operation.

This specific part is compatible with the Komatsu HD4056 model. It is designed to deform slightly upon installation, filling irregularities in the sealing interface to create a barrier against leaks. Proper maintenance involves regular inspection and timely replacement of these seals to prevent fluid loss, which can otherwise lead to system pressure drops or component failure in hydraulic, transmission, or engine circuits.
