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 ...


[ 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 cylin...
