An undermold coupling to couple a hose (1200, 1600) to a hose fitting (1100, 1700) comprising: a tubular portion that defines a cylindrical external surface that is sized to be inserted into a hose interface of the hose fitting, and having a passage formed through the tubular portion between a first open end and a second open end opposite the first open end; threads formed on an inner surface defined within the first open end of the tubular portion to engage a support helix (1280, 1680) on an external surface of an end of the hose (1200, 1600) as a set of threads to retain the end of the hose (1200, 1600) within the tubular portion; and characterized in that a first grating coupled to a portion of the cylindrical external surface of the tubular portion, and comprising a first plurality of elongate portions that are shaped and sized to intermesh with a corresponding second plurality of elongate portions of a second grating of the hose interface of the hose fitting to retain the tubular portion of the undermold coupling within the hose interface of the hose fitting in a position that puts the interior of the hose (1200, 1600) in communication with an interior of the hose fitting through the passage, wherein: each of the elongate portions of the first plurality of elongate portions is curved to follow a curvature of the cylindrical shape of the tubular portion of the undermold coupling; the elongate portions of the first plurality of elongate portions extend in parallel with each other and define a first plurality of slots; each of the elongate portions of the second plurality of elongate portions is curved to parallel a curvature of the hose interface that follows the curvature of the cylindrical shape of the tubular portion of the undermold coupling; the elongate portions of the second plurality of elongate portions extend in parallel with each other and define a second plurality of slots; and when the first grating is intermeshed with the second grating, the first plurality of elongate portions of the first grating extend into the second plurality of slots defined by the second plurality of elongate portions of the second grating, and the second plurality of elongate portions extend into the first plurality of slots defined by the first plurality of elongate portions. a tubular portion that defines a cylindrical external surface that is sized to be inserted into a hose interface of the hose fitting, and having a passage formed through the tubular portion between a first open end and a second open end opposite the first open end;
