The invention relates to a sealing element for forming a liquid-tight seal between two tubular elements running essentially parallel. The sealing element consists of positioning means which are in the form of a flange which is fixed to the inner element of the tubular elements and which is provided on its periphery with a groove which accommodates, in a slightly wedged fit, an endless element of flexible material sealing the groove. On the inside of the groove one or more supply apertures for a compressed medium are present. When the compressed medium is supplied, the endless element of flexible material is moved outwards against the outer element of the tubular elements, in order to form a liquid-tight seal between the two columns. The element can be manufactured simply and cheaply from commercially available materials. The element is also easy to remove from the positioning means and replace. If water is used as the compressed medium, in the event of leakage's, no damage is caused to the products. The sealing element according to the invention can be used in a curd drainage apparatus form removing whey in cheese making. The invention also relates to a device for removing whey from a whey/curd mass, provided with at least one sealing element according to the invention.
