FIELD: sealing rings.
SUBSTANCE: invention relates to sealing rings and can be used to seal transition elements into sealed volumes. To achieve the technical result described below, the sealing ring (1) is made of a toroidal shape from an elastic material with Shore hardness in the range from 20 to 80. N rounded protrusions (2) are evenly located along its inner surface, with N being an integer greater than two. The protrusions (2) are made with smooth transitions to the inner surface of the sealing ring (1).
EFFECT: provided is possibility of simultaneous sealing of the transition element and its fixation from movements.
