Abstract:
A sealing ring made of a rubber-elastic material to provide a media-tight connection betweena spigot (1) of a corrugated pipe (2) having two adjacent corrugated sections (5, 6) having a facing flange (7, 8), a foot section (9) connecting said flanges (7, 8) in transition sections; and defining between each other an annular groove (18) for receiving said sealing ring (17), and a pipe socket (12) having a smooth, essentially cylindrical inside wall (16), which pipe socket is capable of being pushed in a pushing direction (32) onto said spigot (1), wherein said sealing ring (17) is formed mirror-symmetrically and hasa basic body (19) having an inner bead (20, 21) bearing against said foot section (9), having side areas (22, 23) facing said flanges (7, 8), having an annular seal (24 through 27) formed on the outer section of each side area (22, 23) and projecting laterally towards said flange (7, 8), and having an outer sealing bead (28) for bearing against said inside wall (16) of said pipe socket (12), wherein said sealing bead (28) has a central annular bead (29) and on both sides one annular collar (30, 31), respectively, projecting outwardly and laterally, andwherein said sealing bead (28) is capable of being rolled in or over in said pushing direction (32) while elastically deforming said basic body (19), so that the annular collar (30) located upstream in said pushing direction (32) and said annular bead (29) bear against said inside wall (16).
