These Glass 18.8mm Diffuser Downpipes are designed to cool the smoke and give better filtration than a regular downpipe.
The diffuser refers to the holes at the bottom of the downpipe. It works by creating thousands of bubbles as the smoke leaves the downpipe and enters the water. This means the smoke is filtered better and is cooled down a lot quicker.
This downpipe is measured from the base of the 18.8mm stopper to the bottom of the stem.
