Abstract: 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.

Abstract: 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 right cylindrical end portion and a hose ring provided substantially adjacent to the cylindrical end portion whereby a circumferential groove is provided between the cylindrical end portion and the hose ring. The swivel cuff component has a seating portion for receiving the cylindrical end portion of the hose and an annular ring adapted to fit within the circumferential groove of the hose, the annular ring being provided about the hose entrance to the seating portion of the cuff. The cylindrical end portion of the hose is maintained within the seating portion of the cuff by the annular ring being disposed within the circumferential groove whereby the hose may be swivelably rotated within the cuff. The hose end components are extruded with the continuous extrusion blow-molded hose thereby eliminating the need to weld components such as seals.
