1. A flexible, fluid-conveying coupling for coupling a tubular fluid-conveying part to a further fluid-conveying part in a fluid-conveying system, comprising a sleeve, a tubular flange adapted to be fixed to said tubular fluid-conveying part and extending into said sleeve such that said sleeve circumferentially surrounds a portion of said flange with sufficient clearance to allow radial displacement of said flange relative to said sleeve, an elastically deformable seal ring carried by said flange and deformed between the inner periphery of said sleeve and said flange to establish a seal between said flange and said sleeve, said flange being formed with means for confining said seal ring against axial displacement relative to said flange, and means defining first and second bearing seats lying in seating engagement with one another and located axially beyond said sleeve, said first bearing seat having a diameter larger than the inner diameter of said sleeve thereby preventing said first bearing seat from entering said sleeve, said first bearing seat being operatively connected to said flange and said second bearing seat being operatively connected to said sleeve, said bearing seats providing for universal articulation of said flange relative to said sleeve about a center that lies at least in close proximity to a plane normally intersecting the longitudinal axis of said flange and passing through a pre-selected region of said flange, said pre-selected region lying within said sleeve and having an outer diameter that is at least approximately equal to the outside diameter of any other portion of said flange lying within said sleeve.
