The sealing tool comprises a lower tool in which a tray to be sealed can be received and an upper tool including a hood, a sealing component arranged in the interior of the hood, and a sealing component carrier on which the sealing component is arranged. The hood is movable relative to the sealing component and has a gas connection configured for connection to a corresponding gas connection of the tray sealing machine. The lower tool and the hood are configured to form a sealing chamber in a closed state of the sealing tool. The sealing tool further comprises a line connecting the gas connection to the sealing chamber in the closed state. The hood is movable relative to the frame and the sealing component carrier is unmovable relative to the frame.
