Abstract
A sealing element for use in the testing of cigarettes or other rod-shaped articles of the tobacco processing industry has an elastic tubular body with an end portion having an axially movable end wall and an annular lip extending beyond the external surface of the end wall. The latter has a central opening constituting the inlet or the outlet of an axial passage for testing fluid. When the end of an article to be tested is caused to bear against the external surface of the end wall, the latter yields axially of the tubular body and causes the lip to flex radially inwardly into engagement with the periphery of the adjacent end of the article to be tested. In order to reduce the likelihood of damage to the end wall and/or the lip by sharp edges surrounding the ends of certain articles which are caused to bear against the external surface of the end wall, such external surface is provided with an annular recess which is inwardly adjacent the lip and can have a substantially semicircular cross-sectional outline.
