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 10 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. If you’re not sure which size you need, have a look at our handy guide to downstem sizes!
