  • Publication number: 20100127493
    Abstract: A connecting arrangement connects a cylindrical pipe (10) or a pipe section to a connecting body (20). The connecting body (20) has a first conical bore (23), extending away from a face (24), a first cylindrical bore (21) for receiving the pipe (10), which bore is contiguous to the conical bore (23), and a second cylindrical bore (22) that is contiguous to the first cylindrical bore (21) and the diameter of which is reduced. A union nut (30) has a bore (31) for the pipe (10) or the pipe section. The union bore has a threaded section (38) by means of which the union nut (30) can be screwed onto a mating threaded section (28) of the connecting body (20), and a conical bore (33) that tapers in a direction opposite to that of the conical bore (23) of the connecting body (20). Adjacent to the end of the pipe (10) or the pipe section a zone (11) of the pipe (10) bulges outward all around and has a tensioning face (12) that interacts with the conical bore (33) of the union nut (30) and is complementary thereto.

  • Patent number: 5893591
    Abstract: A tube connector (1) has a connecting member (2), a nut (7), and a tube (11). To connect the connecting member (2) to the tube (11), the tube includes a formation (12) with two formation portions (14, 16). The first formation portion (14) has a first tensioning face (13) which extends parallel to an end face (4) of the connecting member (2). The second formation portion (16) has a second tensioning face (15). The tensioning face (15) extends in such a way which corresponds to the second conical bore (9) of the nut (7). The end face (4) includes an annular groove to receive a seal (23). The seal (23) achieves a precision sealing effect. A connector (1) which includes a formation as described above provides advantageous sealing conditions and ensures that the formation cannot be overtightened, especially during repeat assembly procedures.
