The invention relates to a device for channelling, distributing or the like of free-flowing media, e.g. a pipeline, pipe bend, fitting, etc., whose part which channels and/or distributes or blocks the medium consists of a chemically resistant and/or abrasion-proof material. This part of the device comprises at least one thin-walled sleeve, whose side which is directed away from the medium is enclosed in a sealed manner by an element, of the device, which consists of a compression-resistant and/or tension-resistant material.
