In the case of a process for producing an elongated closed duct within a hollow space of a vehicle body, it is provided that the guiding element formed of plastic is equipped on both ends with exterior surrounding flanges. Between the flanges and the vehicle body parts, one surrounding foam seal respectively is arranged which swells up during the painting process in the drying oven at a defined temperature and forms a tight connection between the vehicle body parts and the guiding element.

1. Process for producing an elongated closed duct within a hollow space of a vehicle body, the hollow space of the vehicle body being composed of at least two vehicle body parts, and the duct being formed by a tube-shaped guiding element made of plastic,said process comprising: providing both ends of the guiding element with exterior surrounding flanges, arranging respective surrounding foam seals between the flanges and the vehicle body parts, said foam seals being formed of material which swells up during heating in a predetermined temperature range and, conducting a painting process including drying in a drying oven at the predetermined temperature range to thereby cause swelling of the foam seals to form a tight connection between the vehicle body parts and the closed duct guiding element.
