A diffuser tube, or downstem, that guides the smoke from the bowl under the water. The slits cut into the end break the smoke into several small bubbles instead of one big one, which clearly softens the draw.

An 18.8 mm male joint for the bong and a 14.5 mm female joint for the bowl: the most common combination in glass bongs. This is the longest size in the series and suits bodies with a deeper water chamber. Measure the tube from your old one before ordering.
