Custom Dynavap Stem

Custom Dynavap stem which uses an 8mm OD, 6mm ID silicone tube. To assemble, cut a section of the silicone tube to size and wrap the silicone tube onto the base of your Dynavap head. Then, press the assembly into the stem and it should hold with friction and create an air tight seal against the stem. It is also compatible with a Vaphit head. https://www.vaphit.com/products/vaphit-x-cap-1-0mm-size-holes-1-5mm-thickness-and-vaphit-x-bowl I recommend buying this tube:https://www.amazon.com/gp/product/B08BRGM9T8
