Black Leaf - Inside-Cut Vortex Diffuser Downstem

Using a diffuser downstem is an easy way to add some extra percolation to your water pipe without a heavy precooler or ashcatcher. This vortex diffuser downstem from Black Leaf features 8 specially arranged slits for maximum bubbling!

This piece will also adapt your 14.5mm slide bowls and attachments to any tube with a glass-on-glass 18.8mm joint. They range from 10cm (just under 4 inches) in length for precoolers and small bongs to an impressive 18cm in length for large beaker base tubes.
