A multiple diameter coupling flange, adaptable to opposing flanges of various diameters. The flange is provided with concentric circumferential ribs (1) on its coupling face, each of these ribs corresponding to a different flange standard diameter. To adapt the flange to a given size, the flange may be cut circumferentially around the rib of that diameter. Also provided are series of non-through-going holes (2) for the fastening screws. After cutting the flange to the right size, the corresponding holes will be drilled through. The holes corresponding to different diameters are preferably aligned radially. <IMAGE> |
