ABSTRACT:
A hose structure which is useful as a transitional piece for a connection between two elements of different diameters. The hose has a tapered bore with an oppositely tapered sleeve of deformable material outwardly of the sleeve interior to form a substantially cylindrical outer surface over which the remaining portions of the hose structure are applied. If desired, buoyancy material can be included in the hose structure so that the hose will be buoyant and float in water. The method includes applying an elastomeric liner around a tapered mandrel, applying the tapered layer of deformable material to form a cylindrical outer surface, applying at least one reinforcing layer to the cylindrical surface, applying a cover over the reinforcing layer then vulcanizing the structure to form an integral unit.
