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.degree. 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.degree. flange swivel. The last piece is a 360.degree. bend swivel to a thread, groove or a 360.degree. 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.

[ I claim:] [1.]1. A flexible pipe coupling system comprising a tubular elbow having a turnback rolled and upset at one end for mounting within a recess within a bolt-on flange, and having at the second end an annular groove around an exterior wall portion, the annular groove being spaced inward from the distal end for connecting to a flexible pipe, further comprising a flexible hose coupling and having a flexible pipe with an enlarged end overlying the end of the elbow which has an exterior annular groove, the enlarged end of the coupling having a cylindrical recess for receiving the end of the elbow, and having an annular groove in the recess for aligning with the annular groove in the elbow exterior wall, a shoulder at the end of the interior recess for receiving the end of the elbow, an annular seal disposed between an interior wall of the recess and the end of the elbow within the recess, and a connector disposed in the annular grooves.
