Abstract

A coupling is described (see Figure 1) having part spherical curved end sections (28, 30) which are received in cylindrical passages (16, 22) in two members (10, 20) which are to be joined together by the coupling to provide a continuous passage from one member to the other for the flow of fluid therebetween. The coupling includes at least one annular crease (32) which extends radially outwardly between the opposed end faces of the two members (10, 20) and axial misalignment vibration and distortion due to temperature changes during use are accommodated by means of the crease (32) which allows considerable relative axial and other movements between the two end sections (28, 30). In order to improve the seal between the coupling and the two members, the coupling may be subjected to axial compressive loading and to this end the extreme edges of the part spherical end sections are formed with 45 DEG chamfered surfaces which engage complementary 45 DEG inclined surfaces (14, 24) in the members (10, 20) to be joined by the coupling. The coupling is preferably formed from seamless tubing such as cold drawn seamless steel tube. <IMAGE>
