A pressure device (10) for a sealing arrangement (50) configured to be used in an apparatus for processing pulp, said pressure device (10) including a movable sealing element (70) for mounting in a holder (55) comprising an extended groove (60). The pressure device includes an elastic tube (20) expandableby a pressurizing fluid and provided with rotational symmetric cross-section area (22), at least one collar (30) having a cross-section area (32) corresponding to the first cross-section area (22) of the elastic tube (20) in a non-pressurized state. The collar (30) is arranged to connect the pressurized elastic tube (20) to a nipple element (40; 80) and to fluid-tightly and firmly lock the pressurized elastic tube (20) to the nipple element (40; 80). The nipple element (40; 80) has a nipple (44; 84) arranged for connection to a pressurizing fluid supply and wherein the elastic tube (20) acts on the movable sealing element (70) arranged to fit into the groove (60), having a first sealing surface (71) and a second surface (72) delimiting the groove (60) and in contact with said elastic tube (20), when pressurized, the movable sealing element (70) being pressed in an outward direction by the expanding elastic tube (20) to thereby bear against a surface (80) to provide a seal.
