In order to produce a line element lead-through that is resistant to fire and flue gas for simple installation into one or more paneled drywalls, whereby the line element lead-through can be used in a matching component opening and is also sealed against fire and flue gas when empty, a line element lead-through is suggested with a molded element closed on at least one side of an elastically deformable intumescent material as a sleeve, especially formed as a truncated cone or a cylinder, with the criterion that the opening cross section of the sleeve corresponds to maximum 60% of the cross section of the component pass-through.
