Abstract (en)

[origin: EP0692584A1] The seal comprises an elongated basic element (1) having a polygonal, preferably triangular or trapezoidal cross-section and with at least one inner longitudinally aligned bore-type recess (2). The wall (3) of this recess defines a thin-walled ideal break point (14) with at least one outer face (4) of the basic element. A longitudinally aligned groove type indentation (5) is provided in the base face (11) of the basic element to hold an insert (7) consisting of a sealing material which swells upon contact with water. The outside (8) of the insert can be set back relative to an imaginary plane (10) connecting the lateral edges (9) of the base face (11) of the basic element. The side flanks (6) of the indentation can project wedged shape relative to each other. <IMAGE>
