Abstract:
A method of fabricating a hose end comprising:a. constructing a metal tube having a corrugated wall with successive corrugations defining inner and outer peaks joined by imperforate wall sections;b. terminating the tube adjacent a corrugation peak;c. fabricating a tube end fitting body having a through opening and a seal seat that surrounds the through opening and has a sealing surface that extends outwardly relative to the through opening;d. forming a fitting body extension that projects from the sealing surface and defines a tube corrugation positioner distal the sealing surface;e. assembling a sealing member to the fitting body in contact with the sealing surface and placing the fitting body on the terminated tube end with the terminated end engaging the sealing member and the tube corrugation positioner located at least one corrugation peak from the seal member;f. deforming the extension so that the corrugation positioner moves toward engagement with the tube just beyond said at least one corrugation peak; and,g. resiliently compressing the tube corrugations and the seal member between the corrugation positioner and the sealing surface while deforming the extension.
