    Bowl joint is where the bowl sits in the downstem (the piece that connects the slide/bowl to the water in the bong). The neck joint is how big the downstem is, so it goes from a wide 18 mm hole on the bong, to a 14 mm hole in the downstem. It's a wide to standard conversion downstem. Same thing I have on my ADS

    its called a bushing downstem. its basically a joint inside a joint.
