Abstract
An apparatus and method of producing a multiple compartment corrugated hose with at least one inner corrugated partition. The corrugation of the inner partition is achieved by maintaining a predetermined ratio between the peripheral wall and the inner partition wall. The hose is produced using either a continuous blow molding with internal pressure and/or vacuum assist process where the inner partition is allowed to shrink and relax into a corrugated pattern. Such an hose is flexible in all directions and available for many applications.
