I'm not sure if the threading is universal. I would think it would depend on the manufacturer. Here is a link to a Co. that sells segmented syrians.http://www.magichookahs.com/
Thier is another vendor who sells arguably the best segmented syrians you can get.He is banned from the forum, so I'm not gonna mention his name but check the review section for the "black magic" syrians.You'll find his name there.good luck, and welcome to TEAM SYRIAN!!
