I have been looking for a nice water attachment to use on My LSV and possibly on my Pax. I think I have found the best one he Pinnacle Hydratube but I am unsure of what all I need. I have seen some people put it on each vape but could never figure out how they got it attached. I thi k for the LSV thy just used a 18mm male to make connection. Just want to make sure it wil work before I purchase it. I like the idea is a simple wand style water cooling apparatus and this would seem to fit the bill but I'm open to suggestions. Cheers
