The invention relates to a thermoplastic elastomeric bellow duct () having a corrugated duct segment () interposed between two elbowed segments (), wherein at least one of the elbowed segments () is made of thermoplastic elastomeric and connected to an end section () of the corrugated duct segment () by overmolding the elbowed segment () over the end section () of the corrugated duct segment (), and wherein the end section () of the corrugated duct segment () includes a guiding and sealing arrangement () pointing away from the corrugated duct segment () in a radial direction (). The invention further relates to an air duct () having such a thermoplastic elastomeric bellow duct ().

Thermoplastic elastomeric bellow duct

A plug-in connection between a connecting part and a plug-in part, which are configured to be plugged into one another in an axial direction of the plug-in connection, is provided with a sealing groove disposed between connecting part and plug-in part. A sealing ring is disposed between the connecting part and the plug-in part in the sealing groove. The sealing ring is supported in the sealing groove by the connecting part and by the plug-in part, respectively, in a radial direction of the plug-in connection and exerts a sealing pressure in the radial direction. The sealing ring has an omega-shaped cross section with a rounded body portion having an open side and with supporting legs connected to opposed ends of the rounded body portion at the open side of the rounded body portion. The open side of the rounded body portion faces outwardly in the radial direction.
