Sensor/thermal bulb from a capillary tube. Likely from a refrigerator.

From a quick search, it is used to control the flow of refrigerant based on its temperature. The tube deforms based on how hot or cold the refrigerant is, and there are contacts on the tube to switches that permit or resrrict coolant flow

In other words, it's a simple thermostat
