First of all, this part does not come with the bottom pipe tool, in spite of it being pictured in the description. Secondly, it attaches well to the pipe itself, but not to the part that you want to use it with. Too loose. Part will fall off, unless you stick it down with tape. I had high hopes for this HomeVac H30 and its accessories, but I won't be buying anything to do with this model again, if it were to break. :-(
