         3 . The sanitary insert assembly ( 1 ) according to  claim 1 , wherein more than half of a cross-sectional area ( 10 ) of the sealing ring ( 7 ) is arranged outside a thread area ( 9 ) radially occupied by the thread ( 6 ). 
     
     
         4 . The sanitary insert assembly ( 1 ) according to  claim 1 , wherein the sealing ring ( 7 ) is positioned one of upstream or downstream of the thread ( 6 ) in a screw-in direction. 
     
     
         5 . The sanitary insert assembly ( 1 ) according to  claim 1 , wherein a groove base ( 11 ) of the thread ( 6 ) is arranged outside a sealing ring area ( 12 ) radially occupied by the sealing ring ( 7 ). 
     
     
         6 . The sanitary insert assembly ( 1 ) according to  claim 1 , wherein the sealing ring ( 7 ) has at least one of a round, wedge-shaped, or rectangular cross-sectional area ( 10 ). 
     
     
         7 . The sanitary insert assembly ( 1 ) according to  claim 1 , wherein at least one of a) the sealing ring ( 7 ) is pressed at least partially in an axial direction against a counter-sealing surface ( 21 ) or b) a sealing surface ( 26 ) on the sealing ring ( 7 ) has a curvature. 
     
     
         8 . The sanitary insert assembly ( 1 ) according to  claim 1 , wherein a screw sleeve ( 13 ) is formed. 
     
     
         9 . The sanitary insert assembly ( 1 ) according to  claim 1 , wherein the thread ( 6 ) is an external thread. 
     
     
         10 . The sanitary insert assembly ( 1 ) according to  claim 8 , wherein the screw sleeve ( 13 ) is at least one of snapped, welded, pressed or manufactured in one piece with a jet regulator ( 14 ). 
     
     
         11 . The sanitary insert assembly ( 1 ) according to  claim 8 , wherein the screw sleeve ( 13 ) has tool engagement surfaces ( 15 ) which are formed in at least one of an axial or radial direction at an outflow-side end ( 25 ) thereof in an assembly position which are so formed to interact with a tool such that a screwing movement of the sanitary insert assembly ( 1 ) is adapted to be driven by the tool. 
     
     
         12 . A sanitary fitting ( 20 ) comprising a fitting thread ( 27 ), and an obliquely oriented counter-sealing surface ( 21 ) adjoins the fitting thread ( 27 ). 
     
     
         13 . The sanitary fitting ( 20 ) according to  claim 12 . wherein a fitting thread area ( 28 ) radially occupied by the fitting thread ( 27 ) is less than half as large as a sealing surface area ( 29 ) radially occupied by the counter-sealing surface ( 21 ). 
     
     
         14 . The sanitary fitting ( 20 ) of  claim 13 , further comprising a sanitary insert assembly ( 1 ), wherein the counter-sealing surface ( 21 ) between the fitting ( 20 ) and a sealing ring ( 7 ) of the sanitary insert assembly ( 1 ) in the assembly position is arranged on an outflow side of a thread ( 6 ) and is designed such that the sealing ring ( 7 ) at least one of contacts the fitting ( 20 ) at at least two points ( 32 ,  33 ) axially and radially spaced apart from one another or is angled obliquely in a screw-in direction such that a diameter ( 30 ) of the contact area ( 31 ) varies in the screw-in direction. 
     
     
         15 . The sanitary fitting ( 20 ) according to  claim 14 . further comprising at least one shoulder ( 22 ) on an outflow side to the sealing ring ( 7 ). 
     
     
         16 . A sanitary insert assembly ( 1 ), comprising:
 a thread ( 6 ); and   a sealing ring ( 7 );   
       wherein a thickest point ( 8 ) of the sealing ring ( 7 ) is arranged radially outside or inside at least one of a thread tip ( 36 ) or a thread root ( 37 ) of the thread ( 6 ). 
     
     
         17 . A sanitary insert assembly ( 1 ), comprising:
 a thread ( 6 ); and   a sealing ring ( 7 );   
       wherein more than half of a cross-sectional area ( 10 ) of the sealing ring ( 7 ) is arranged outside a thread area ( 9 ) radially occupied by the thread ( 6 ).
