Abstract
A packing structure has a core element of a material having a high fluid impermeability, and a thin coated rubber layer formed thereon to cover at least its sealing surface and having a glass transition temperature which is lower than the lowest temperature allowable for the packing structure. It shows a high sealing property even at a low temperature and a high fluid impermeability when used for sealing e.g. a pipeline for conveying fuel in a motor vehicle.
