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.

Multiple compartment corrugated hose

An aquatic vacuum hose swivel cuff coupling comprises, in combination, a blow-molded vacuum hose and a molded swivel cuff. The hose includes one end which terminates as a corrugated end portion having circumferential grooves therein. The swivel cuff component has a seating portion for receiving the corrugated end portion of the hose and at least one annular ring adapted to fit within the circumferential grooves of the hose, the annular ring being provided about the hose entrance to the seating portion of the cuff. The corrugated end portion of the hose is maintained within the seating portion of the cuff by the annular ring being disposed within the circumferential grooves whereby the hose may be swivelably rotated within the cuff. The corrugated end portion of the hose is extruded with the continuous extrusion blow-molded hose thereby eliminating the need to weld components such as seals.
