This is a new lower duct internal vacuum white replacement hose. It is a replacement piece that is flexible oval like hose that is 2. 3/4” Inside Width. Each end has different sized ends. See measurement photos. These are hard to find. It is not thin and is substantial. It goes from the vacuum head to the bag on the bottom piece of the vacuum. I am not sure which vacuum upright it goes on so see photos for your replacement size. I do have two of these. The other if needed is an additional fee. Message me for exact. I am not a vacuum seller. It is an estate item.
