I did five small zip ties from end to end. Worked great.
Pinan, I'm just pointing out that if you don't have gaps, you can use superglue. My tubing was a dead fit, so epoxy was going to just scrape off and make a mess while trying to put it down the hole. I just dropped the tube in (after gluing knob end cap on) and wicked the superglue between the tube and the wall.
Of course, the problem with superglue is you have to work fast and neat. But you can control Z a bad assembly by putting it into a jar of acetone.
