Understand your delima korova8...
As we've entered the world of tanks, we've also entered an alternate universe... one of tolerances! LOL Everything on the tank is allowed a tolerance distance/span allowance from the poly tubes to our machinist that makes our caps. So although the delrin and SS is suppose to be the same dimensions... it's was obvious when we went to put a set of SS in the pyrex it wasn't going to go easy. Which is a good thing, and what we're looking for so nothing leaks. But NOT in the case of pyrex.
We have recently changed our o-ring kit. We had some o-rings custom made to help with the issue of tolerance, but the #4 o-ring is for the outside to make it snugger in poly and SS tubes so it won't be a help in the pyrex. Sorry not a solution yet to make the SS work with pyrex. Simply because 1/2 of our stock on our very first order of pyrex showed up at our door broke...very, extremely, incredibly poor packaging. And we don't know if we are going to make another run of them. So in the mean time delrin should work, but it's not recommended to try the SS. Wish I could have a different answer for you. We could use some feedback on the pyrex though, so we can decide if were going to continue developing them.
Sorry, but I hope this helps making your decision.

OK guys. I am SO CLOSE to pulling the trigger on a Lil Mamma. Here is my predicament. I want a tank exclusively for my cinnamon juices so I found that Big Daddy vapor offers pyrex and stainless steel tubing. I REALLY want the stainless caps with a pyrex tube. I read that it is not recommended(for obvious reasons) but is pretty much a guarantee that it WILL break against the stainless caps? Or if Im careful with it I should be fine? Any advice would be greatly appreciated!
Thanks in advance!
