1. An electric machine for an electric vehicle, comprising:
a housing;
a stator rigidly arranged on the housing;
a rotor rotatably supported on the housing, wherein the stator and the rotor bound a radial gap; and
a canned tube arranged in the radial gap and fluid-tightly abutting the housing at an end such that the canned tube fluid-tightly separates a wet space through which a coolant can flow from a dry space,
wherein the stator is arranged in the wet space and the rotor is arranged in the dry space,
wherein the canned tube on an outer peripheral surface and/or the stator on an inner peripheral surface comprises an elastically deformable sealing element,
wherein the sealing element is elastically deformed in a finally mounted state of the canned tube between the outer peripheral surface of the canned tube and the inner peripheral surface of the stator such that a gap between the outer peripheral surface of the canned tube and the inner peripheral surface of the stator is sealed.
