Cartos are pretty much the same. There may be some solder on the tube too, but I'm pretty sure they solder 1st then add the tube. You can push the center post out first from the inside, by gently rotating and increasing pressure with a blunt tool. Then with good tweezers get the rubber insulator out and get to work on the rest, vent, vent, vent. I can't get the end of the tube to peel (run out of tube) without doing a diagonal slice in the SS tube first, as close to the connector as possible without messing up the connector's shoulder. Good luck!
