This product is supplied as an O-ring identified by part number 6217-21-6880. The available product data does not specify the sealing location, cross-sectional diameter, inside diameter, outside diameter, material compound, hardness, operating temperature range, or fluid compatibility. These parameters should be verified against the removed part and the service documentation for the applicable Komatsu equipment before installation.

The models above are the equipment and engine applications provided for part number 6217-21-6880. The model references are retained as listed because the available data does not define a narrower machine configuration, production range, component group, or serial-number limitation.

HM350 and HM400 are listed as compatible Komatsu machine models. SA6D140E, SAA6D140E, and SDA6D140E are listed as compatible Komatsu engine model references. The description does not identify whether the O-ring is installed in the engine, hydraulic system, fuel system, cooling system, transmission, or another component, so no installation position is specified here.
