ABSTRACT:
An annular packing (30) has a cross-section in the form of a dumbbell including two enlargements (31, 32) connected by a neck (33). In a preferred embodiment the enlargements exhibit a polygonal cross-section. The packing advantageously replaces an O-ring seal in which the interior diameter of the ring is large relative to the diameter of the cross-section of the ring. The packing is arranged between two parts driven at different speeds, in precision mechanisms or in horology.
