The basis of the Düker thrust-resisting joint SMU for screwed connections is the locking ring with locking teeth. This locking ring takes up the thrust forces. With the sliding bevel at the screwed ring, a radial force is produced with the locking ring, which results in a secure locking with the spigot end. At the same time an axial force is caused, which is transmitted unreduced to the sealing ring. At this place the necessary sealing effect is induced.

The system Düker SMU is ideal for the connection of grey cast iron with modern pipe materials and is available for the nominal diameters DN 40 – 65.
