Wear A Fucking Mask!
This is my recollection. Starting with the Zion, Ryan used a US standard ground glass joint that was 19/22mm. (that standard is actually 18.8mm but people call it 19 or 18) The original Milaana, the original Splinter and then the Ryan's US Custom Z was also 19/22mm. The reason for the warning was that the most common GG joints were ISO standard rather than US standard, and those are 19/26mm which is too long for the then existent RBT vapes. Then, in what I think was an effort to make some more room inside the body of the Splinter Ryan changed the joint to a 19/19mm joint, and that was the size the V1 assembled in China went with as well. So, if you have 19/19mm jointed stems that should work fine with ANY RBT vape because shorter is not a problem as 19mm is plenty of depth to grab the stem.Ok thanks, but on vapefiend is however specify :
Warning: These mouthpieces may not fit US custom Splinters and Splinter Z sold prior to January 2019.
How can I know if it will go on my unit (no recorded date) ?
What is the : Do not use standard 19mm in notice ?
All the RBT vapes I have, the original Zions, the original Milaana, the original Splinter, my US Custom Z, and interestingly my Splinter Z V2 are compatible with all my 19/22mm stems, many of which I had customed to work with these vapes. I went out of my way to be sure I wouldn't be forced into the 19/19 restriction that occurred later because I had custom stems. That meant that there were certain, later, RBT vapes I couldn't get.
