ABSTRACT OF THE DISCLOSURE A pivotal screwed fitting for joining pipes has a hollow body including a coupling nipple for attachment to the end of one of the pipes. The hollow body is adjustable about the axis of the coupling nipple. The fitting further has a hollow screw arranged in the hollow body. The hollow screw has a threaded end portion to be screwed into another one of the pipes for tightening the hollow body to the last-named pipe. The hollow screw has a plurality of ports which maintain communication between an axial blind bore of the hollow screw and an annular channel defined together by the hollow body and the hollow screw. A connecting passage defined by a wall of the hollow body maintains communication between the coupling nipple and the annular channel. The passage widens from the coupling nipple in the direction of the annular channel; the wall defining the connecting passage has an at least approximately rotationally symmetrical configuration with respect to the axis of the coupling nipple of the hollow body. - 1 -
