Abstract: A rinse assembly for a commercial washdown pre-rinse system is described, including a flex hose and live swivel fitting. The incorporation of an infinitely rotatable swivel fitting at the base of the flex hose and/or adjacent the spray nozzle releases torsion within the flex hose and prevents damage to the hose and surrounding metal coil due to shear stress. A modular rinse assembly in which components may be easily added, removed, or replaced is described, as well as a method to retrofit existing rinse assemblies to incorporate a live swivel fitting.
