Alsome Sherlock that fits 14mm and the hydro vaperizor loving it along with all his vaporizers
Wonderful collaboration with Simrell and N3rd! Works great, very sturdy and just works like you expect it would!
This airflow valve was a must have for me. I mainly use it when running things through a water piece. So far, it works great with all my Simrell Heritage and Dynavap stems. I like to either close it completely or leave it a bit open.
