<p>The sealing ring is open at one side and comprises two complementary ends joined with no linear gap between them. Each of the ends is divided vertically into two segments (11, 12, 13, 14) protruding from the main part at different lengths. Each of the segments (11, 12, 13, 14) is designed as a step, one of them in an upright position, the other upside down. The opposite end is designed in a reciprocal shape resulting in overlapping areas in order to provide a particularly safe sealing area.</p> |
