ABSTRACT:
A hose connection for high pressure installations and a method for making the same in which a nipple provided with externally projecting beads or ribs of annular configuration is initially internally expanded to substantially the inner diameter of the hose by an expanding tool while the hose is constrained against radially outward movement by a cylindrical sleeve-like member having a smooth internal surface. The sleeve-like member secured to the nipple is subjected to at least one subsequently realized inwardly extending deformation which may be made by a crimping tool; in case of annular rolled-in grooves, the latter are preferably so arranged that the deepest point of the annular grooves are located between peaks of adjacent beads or ribs. By appropriately coordinating the expansion of the nipple and subsequent contraction of the sleeve-like member to the dimension and characteristics of the hose material, a high pressure connection can also be realized for a hose reinforced by a metallic sheath which avoids any significant dislocations and structural changes in the reinforcing sheath.
