ABSTRACT:
The turnable connections for pipes and hoses mainly consist of connection nipples which can be linked to the end of these connections and which are partly amable as well as equipped with at least one sealing ring and a connection nipple with a union nut, with the amable tap-type connection nipple showing two ball-shaped bulged sections with different radii but the same center as well as a union not corresponding with the ball-shaped section and the overall sleeve-type connection nipple having a thread on the outer surface, which as well has a corresponding ball-shaped section with the same center M. In order to achieve a better turnability of the connection in the operating condition with an improved sealing and contract retention, a circular gap (13) was integrated between the ball-shaped section (3) of the tap-type connection nipple (1) and the ball-shaped section (4) of the overall sleeve-type (2), and in the overall section (4) a circular recess with a supporting ring (14) and a sealing ring (6) was integrated, with the sealing ring (6) being located at the ascending part of the ball-shaped section (3) of the tap-type connection nipple (1).
