Although many of the DIN32676 flange outer diameters are dimensionally the same as the OD tube flanges, the internal diameter is always different. Exceptions are the DN10 –DN20 (34mm) and the DN80 (106mm), these have different flange diameters. Many people utilize standard OD tube orifice plates for DIN & ISO flanges because they do fit, however the internal diameter of the elastomer is either too big or too small.
