IDEAL FOR THE CONNECTION OF

GREY CAST IRON WITH MODERN PIPE MATERIALS

Düker SPEZIAL makes the thrust-resisting end connection of flanged sockets and collars possible. For the installation of double socket collars, only the first side can be installed with the DÜKER thrust-resisting joint SMU. For the other side the thrust-resisting joint Düker SPEZIAL is needed, because in this case it has to be sealed first and locked afterwards.
 
This thrust-resisting joint has been proving itself over years within the nominal diameters of 300 – 400. Since 2007 we offer Düker SPEZIAL additional for the nominal diameters DN 80 – 250.
