They don't have sleeving for tubing but you could order sleeving and make it fit over tubing. The only problem would be the ends that would fray a little and be hard to make look neat. But the overall look would be awesome I am sure. Heck I am thinking of doing it myself now! :bleh:
I sleeved my tubes and like the effect, but there is a few things to consider first. The first thing is compression fitting are going to suck, the sleeving adds to much for the compression fittings to tighten up nice, it will also cause it to fray. Adding heatshrink just adds more to the dimension so you will need to heatshrink it above the fitting.
Heres the major thing I found, I use feser uvblue tubing and carbonfiber sleeving, the glow it nice and bright but subtle BUT switch out the carbonfiber sleeving with some plain carbon colored sleeving and the effect sucks IMO the sleeving just mutes the UV effect and you will find it lacking, I did and I just wanted subtle tones not bright glowing tubes.
IMO the key is the carbonfiber sleeving, I would/will do it again but not if I have to use standard sleeving.
