In most cases, the central vac companies employ out-sourced parts for their units. It could be a Eureka (very common), Electrolux, Panasonic, or other manufacturer's nozzle. A reputable vac. repair place should be able to help identifiy and locate the parts you need. When someone brings a central unit to me for repair, almost every time I can tell who made it just by looking at it, because they are simply re-named parts.
