The invention relates to a sealing device (24) for separating two spaces at different pressures through which a profiled object (12) having a concave cross-section is conveyed. The device (24) includes a pair of conveying rollers for the profiled object (12), having axes that are substantially parallel to each other and that are perpendicular to the conveying direction. The axes of the rollers are spaced from each other so that the profiled object (12) can be conveyed therebetween and so as to induce the plastic deformation of the profile by compression between the two rollers so that the rollers and the deformed profile contribute to the tightness between the two spaces. The invention also relates to a treatment facility (10) that includes said sealing device (24).
