Problem

You have two sewer pipes with a different outside diameter and need a solution up to 2,5 bar.


Solution (1/4)

Use the Crassus Standard Coupling Type 2B Plus. Place the standard coupling in the first step on the pipe with the biggest outside diameter.


Solution (2/4)

Now push the bush on the sewer pipe with the small outside diameter.


Solution (3/4)

Finally you can push the pipe with the installed bush into the standard coupling. Pay attention to the recommended tightening torque.


Solution (4/4)

Done! You have now connected both sewer pipes with a standard coupling and bushes.
