The invention provides a one-piece flex pipe connection that has a bend, and any angle to a termination of a thread, groove or a 360° swivel flange. Additionally the invention provides a flex pipe coupling with a bend and with one end having a groove clamp connection and the other having a thread, groove or the 360° flange swivel. The last piece is a 360° bend swivel to a thread, groove or a 360° flange swivel. A preferred flex pipe coupling apparatus has a connector body with angularly related ends and with a central portion between the ends. At least one of the ends has a cylindrical recess. A shoulder at an axial end of the recess near the central portion cooperates with an end of a flex pipe inserted in the recess. An annular seal receiver in the cylindrical recess near the shoulder holds a resilient seal for sealing the end of the flex pipe. An annular groove in the recess cooperates with an annular groove in the flex pipe to receive and hold connecting elements for connecting the flex pipe to the connector. |
