A sealing interface seals between an air dryer cartridge and a base for an air dryer cartridge. The sealing interface has at least one sealing element, at least one sheet metal element on the air-dryer-cartridge side, and at least one base-side extension, wherein the base-side extension has a bearing surface for the sealing element, which bearing surface is directed radially inward relative to the longitudinal axis of the base and of the air dryer cartridge. The sheet metal element is fastened on the air-dryer-cartridge side, and, in the assembled state, the sealing element presses against the bearing surface. A holding element is provided which, in the assembled state, is arranged such that the sealing element is held between the sheet metal element and the bearing surface at least partially in the axial and/or radial direction relative to the longitudinal axis by the sheet metal element and/or the holding element.
