The invention relates to the field of materials science and to a device for reducing pressure in cavities in media at higher temperatures, such as those devices which can be used for devices for hot-dip coating metal materials in the metal processing industry for example. The aim of the invention is to provide a device by means of which pressure can be reduced in the cavity of the hollow bodies in a reliable and controlled manner and simultaneously the penetration of the media can be delayed or completely prevented at the higher temperatures. This is achieved by a device for reducing pressure in hollow bodies in media at higher temperatures, wherein at least one opening to the cavity of the hollow body is provided in hollow body regions which are not used for the intended application, said opening being closed from the medium surrounding the hollow body by at least one component made of a gas-permeable metal or ceramic material.
