ABSTRACT:
An apparatus and method for producing an hydraulic hose having ends of different internal diameters. An uncured hose is produced by conventional extrusion. The uncured hose is placed upon a mandrel having a reduced diameter end. That end of the uncured hose proximate the reduced diameter of the mandrel is covered by a heat responsive shrink tube. The shrink tube is heated to mold the end of the hose about the mandrel. Thereafter, the hose is vulcanized.
