A pipe joint for air conditioners, whose joint portion (1) is equipped with an annular recess (2), from where a perpendicular or inclined surface portion (3) rises to the surface of the joint portion and to the recess a flexible sealing ring (4) is fixed, whose sealing flange in the unloaded state extends approximately perpendicularly from the joint portion, and in the loaded state, when the pipe element (5) is pushed on top of the joint portion, bends against the surface portion (3). The radial length of the sealing flange (4) is essentially longer than the length of the surface portion so that its end gets between the outer surface of the joint portion and the inner surface of the pipe element (5). |
