Additionally the invention provides a flex pipe coupling (30) with a bend and with one end having a groove clamp connection (32) and the other having a thread, groove or the 360° flange swivel (22). The last piece is a 360° bend swivel to a thread, groove or a 360° flange swivel (22). A preferred flex pipe coupling apparatus has a connector body (14) with angularly related ends and with a central portion between the ends. At least one of the ends has a cylindrical recess (144). A shoulder (146) at an axial end of the recess near the central portion (138) cooperates with an end of a flex pipe inserted in the recess.</p> |
