Abstract: A crimp machine includes a linear mover that forces a ram plate assembly toward a base plate to radially contract an insert. The insert has an inner surface defining an interior dimension that mates with a fitting and crimps the fitting onto a flexible hose as the insert is radially contracted. To adjust for fittings of differing dimensions, a plurality of inserts of varying inside dimensions may be used. To make the crimp machine adjustable for a wide range of fitting dimensions, a plurality of adapter rings of differing inner diameters may be employed. Each adapter ring is removably interposed within a base plate aperture and has a differing inner surface for mating with an insert of desired proportions.
