Component assembly for a motor vehicle

A component assembly for a motor vehicle includes a housing and an actuating element that is rotatable about an axis. The assembly also includes an actuator which is configured to cause rotation of the actuating element. The assembly further includes a rotatable shaft which extends along a shaft axis and is disposed between the actuating element and the actuator and which is coupled to the actuating element and the actuator. The shaft is guided through a first through opening in the housing. A sealing system which seals a first end of the first through opening in relation to a second end, facing away from the first end, of the first through opening against liquid media passing through is provided in a radial direction that is perpendicular to the shaft axis so as to be between the shaft and a first internal wall of the first through opening. The sealing system has a first sealing element having a second through opening through which the shaft is guided. The first sealing element has a radially inward-pointing first internal side as well as a radially outward-pointing first external side. The first sealing element by way of the first internal side in a sealing manner encircles a shaft external side of the shaft. A first material of the first sealing element largely comprises polytetrafluoroethylene (PTFE).
