<p>PURPOSE:To provide such a mating flange that is excellent in workability in addition to positive sealability by ameliorating the mating flange available at time of connecting a connected tube to a flexible tube fitting by means of flanging. CONSTITUTION:A mating flange 1 is composed of a flange body 2, formed into a ring with a smaller inner diameter than an outer diameter of an elastic flange 13 and being free of separation and a ring body 3 with a larger inner diameter than the flange body 2 as concentrically combined together, and plural pieces of bolt coupling holes are installed in these flange and ring bodies 2, 3 at each corresponding position. With this constitution, the elastic flange is easily attachable to an interval between a connected tube and the mating flange as keeping the extent of high sealability intact.</p> |
