Abstract
The present invention relates to a leaktight seal with a lip capable of gripping a shaft end and being fitted behind a cap. When the cap is in place covering the shaft end and closing the housing, it presses on a stop flange of seal and pushes the lip outwards so that the rotation of the shaft end causes no wear on the seal. When the cap is removed, the housing remains open but the lip grips the shaft end and restores the leaktight seal. This fitting is of particular use for shaft ends fitted with a key slot used for manually rotating a rotating machine during the inspection phase of servicing, the shaft end being driven during normal use of the machine.
