ABSTRACT:
An insert fitting for a convoluted hose end includes a generally cylindrical nipple insert having two spaced annular sealing surfaces and a relief region situated between the surfaces. The relief region has a diameter less than that of each of the sealing surfaces, each of the sealing surfaces being radially equidistant at all points from a longitudinal axis extending through the center of the insert. In the preferred form, each of the spaced sealing surfaces has a longitudinal width in the range of seventy-five to one hundred percent of the pitch width of the convoluted hose.
