Abstract:
A junction for a flexible tube for high pressure fluids, comprising a sleeve (11, 31) pressed down onto said flexible tube, a connection element (12, 32) of said flexible tube for coupling with said sleeve (11,31), wherein a rotating female threaded element (13, 33) is connected to said connection element (12, 32), said connection element (12, 32) of said flexible tube being associated with a threaded end element (14, 34), wherein a hydraulic seal is formed between said threaded end element (14, 34) and said connection element (12, 32), said hydraulic seal being formed by the coupling of truncated cone surfaces (15, 35), that are present on said threaded end element (14, 34) which has a connection means that is associated with said connection element (12), wherein said truncated cone surfaces (15, 35) and said connection means are tightened together using a suitable tightening coupling wherein said connection means that is associated with said connection element (12) comprises said truncated cone surface (15) and a second truncated cone surface (16) which is present on said connection element (12), said connection element (12) having a circular hollow space (17) adapted for holding an O-ring gasket (18) wherein said O-ring gasket (18) rests on an external surface (20) of said end element (14), and consists of a material resistant to high pressure fluid which forms a further hydraulic safety seal fluid with the aim of a further safety hydraulic seal wherein said truncated cone surface (15) and said second truncated cone surface (16) are tightened together using a suitable tightening coupling.
