No problem at all and yes that is the qualifier on these atomizers. If they sell with Metal tube or plastic sections then there is no expectation of them being designed properly for glass so that is something folks should look for when purchasing them if they want to be able to use glass on their device as most do. Even
vaping non reactive
eliquids such as my own I feel much more comfortable using glass plus it just looks nice.
Now if a device is sold with a glass section then it should be designed to properly fit glass within the range of top tier glass makers specifications. Sadly this isnt always the case, I have purchased devices that came with glass in the box that would not fit and I have measured one that due to poor QC or whatever reason was so close to nominal leaving no room for tolerance that the majority of glass would not fit on it. I can only assume that when sold new they simply kept trying until they found one that fit. Unfortunately we cant keep sending out free replacements until one fits.
It really is simple for the makers of these devices, make any metal part going into the tube section 0.25mm (minimum) under the nominal standard glass tube size and use a 1.5mm CS (or thicker) oring.
Those two things would make for a much better product serving the wider range of their customers. For customers who dont want glass buy anything you like but dont expect glass to fit it as there are limited sizes and a greater manufacturing tolerance over PMMA or Steel. For those who do want to use glass use your voting dollars to push for those two things to be a standard by using atomizers that meet this design criteria.
I would remiss if I did not mention end sealing atomizers (liquid seal is on the end of the tube rather than the ID) and devices with a metal sleeve. Most end sealing atomizers have a lip the OD of the tube must go into and of course sleeves must allow the tube to go inside of it. These cases are the same only they deal with the OD of the tube so they need to be 0.25mm over nominal size.
Also, I use 0.25mm as kind of a catch all but each tube size has its own manufacturing tolerance and most are greater than 0.25mm but the vast majority of glass in the range of sizes we typically use should be within a quarter mm +\- most of the time. The 22 x 1.8mm glass tube has about the best tolerance, I suppose it has to do with how well the machines that draw the molten glass are able to keep it within that tight range. Thicker or thinner wall or larger diameter and the tolerance begins to get larger.
Lastly (and sorry this has gone long) fused quartz should never be used. This is just a come on buzzword thing with no benefits for vapers in terms of the glass itself and quite expensive to deal with. Fused quartz sizes do not for the most part cross over to BoroSilicate (PYREX) sizes so if you purchase an atomizer sized for this glass you are pretty much stuck with it.
