ABSTRACT:
A unitary supply means for two separate liquids comprising a flexible supply hose unit defining at least two conduits generally of different sizes, one of which preferably is transparent, having an integral common wall reinforcement of extra thickness between them urging the hose to straighten against kinking and providing short free ends for each conduit of different lengths for mating longitudinally spaced series of connections or couplings with appropriate liquid supplies and mixer inlets, the couplings in the solute line being self-tightening under longitudinal stretch strains, and preferably in combination with means for adjusting the relative rates of flow of the liquids through the several mixing chambers.
