Abstract
A turbomachine element includes a stator, a rotor, and a first sealing means for sealing between the rotor and the stator. The element is arranged to be active when the rotor is in the operating position of same around the axis of rotation thereof. The element includes an auxiliary pressure sealing means, sealing between the rotor and the stator and is arranged so that the two sealing means are active when the rotor is placed along the axis of rotation thereof during an assembly operation in a test position. In the test position, the rotor and the stator form an enclosure between said two sealing means.
