Abstract
A seal for concrete pipes wherein the sealing function can be controlled by varying the relative change of length under compression, the hardness of the elastomeric material or a combination of the two. The elastomeric body is of wedge-shaped cross section wherein the wedge-shaped end is positioned at the front in the direction of introduction of the pipe end. The elastomeric body further includes a base end having an introduction opening to a reception space. An attachment portion is anchored in the reception space of the elastomeric body and is adapted to control the degree of compression of the elastomeric body.
