Abstract
A rotatable coupling for a vacuum cleaner is described. The rotatable coupling includes: an inner conduit having an outer surface; a compressible strip disposed on the outer surface of the inner conduit; an outer conduit adapted to snugly fit over the strip and the first conduit. The rotatable coupling can include a non-reactive high-viscosity lubricant disposed on the outer surface of the inner conduit adjacent the strip. The outer conduit of the coupling can be rotatable about the inner conduit and an interference fit is formed between the inner conduit and the outer conduit.
