I'm happy to help, as many did for me, a couple of years ago... The ssv wands are 18mm ground glass joints, So yes they are usefull for many vapes... I love using my ssv wand.. it has very thick walls, brilliant heat retention for glass.. I also like the secondary screen inside.. This gives you the option of a mega pack... (Filling the basket, and the space behind it) Or you can just fill the back section, and just give a shake between hits.... Many options, and it's all about variety.... https://www.namastevaporizers.co.uk/collections/7th-floor-accessories/products/ssvwhipwandset Oh and I use silicone with an 8mm internal diameter... This works well for most things... https://vapefiend.co.uk/platinum-cured-silicone-tubing Hope this helps..
