This is the small hose located on the chassis of the machine, it is the hose that transfers the suction between the cleaner head and the main hose. This is not the main hose located at the back of the machine, nor is it the lower duct hose that is located near the side of the ball.

Will fit all versions of the Dyson DC25 ball vacuum. The hose has been fully checked and cleaned, some marks may remain, but this does not affect performance
