Abstract: A swage visual indicator for a fluid coupling is disclosed and related methods. The swage visual indicator is achieved by a non-destructive visual indication of a swaging process by one or more swage apertures formed through a flange filled with an indicator material. The swage apertures communicate with swaging grooves of the fluid conveying components being joined.

Abstract: A flexible pipe joint has two annular elastomeric flex elements stacked in a co-axial fashion at an inner radius from a common center of rotation, and at least one elastomeric flex element disposed at an outer radius from the common center of rotation. The flex elements at the inner radius are coupled mechanically in series between the extension pipe and the housing of the flexible pipe joint, and the flex element at the outer radius is coupled mechanically in parallel with the series combination of the inner flex elements.
