Abstract

Device for connecting tubes together, characterized by the fact that the connection device comprises a fitting which is made up of a tube that has an axial hole with a flare and on the outside a helical thread and at the bottom of the hole there are another concentric with a smaller diameter for the passage of fluid and the difference in diameters of the two concentric holes determines an annular step on which the end of the tube inserted into said flared circular hole rests, being strung on the part of the tube located in the fitting two trunk ferrules- They are superimposed so that the frustoconicality of the upper one goes into the frustoconicality of the lower one when the inverted cup-shaped clamping nut with threaded internal walls and with an axial hole for the passage of the tube is threaded to the fitting and the internal bottom of The cup tightens against the upper ferrule, which, as it enters the conical walls of the lower washer, presses against it and against the wall of the tube, producing a slight controlled deformation and, as a consequence, the second ferrule in turn slides on the flare of the fitting and also It also presses against the wall of the tube, thus achieving tightness at three separate points of the device, and two of these points prevent the formation of movements and vibrations of the tube, and the intermediate also acts as an element to obtain additional resistance to pressure.
