ABSTRACT:
A metal hose comprises a metal tube having an annularly corrugated wall, a fitting body, an extension that projects from the fitting body, and a sealing member. The fitting body defines a sealing seat for the sealing member. The extension projects from the body about the tube and defines a corrugation positioner distal the fitting body. The extension is deformed to shift the corrugation positioner toward engagement with the tube and resiliently compress the tube corrugations between the positioner and the sealing member. The resiliently compressed corrugations urge the sealing member against the seat for sealing the juncture of the fitting and the tube. In one embodiment a reinforcing shroud surrounds the tube and extends into the fitting. The fitting secures the shroud in place. The corrugation positioner compresses the tube corrugations through the shroud so the shroud is clamped and secured in place by the positioner at a location spaced axially from its end within the fitting.
