One of the basic requirements in the private and communal ground drainage field is that the pipes do not leak. The new patented 3 lip seal can now be used more quickly than ever before and guarantees secure sealing even under the most adverse conditions. It is the result of a long development phase. The decisive improvements are achieved by the special design of the ring.

1. Tensioning lip and Retaining lip

The tensioning lip prevents dirt collecting between the pipe wall and the seal.

The retaining lip causes the tensioning lip to be pressed against the foremost edge of the bead. This stops the sealing ring from being pressed out or rolling.

2. Wiping lip

The wiping lip serves to keep back any dirt on the pipe.

3. Sealing lip

The sealing lip assures a permanently tight pipe connection. Leakage test according to DIN EN 1610 with air and water from 0.05 to 0.5 bar, and under a vacuum. (System test 3.0 bar MPA Darmstadt).
