Two days from being exactly a year ago now. Original post was 8/4/11I've seen plenty of clear tubing. I've never seen it in a material I would want to use, but it's not hard to find clear tubing. As we seem to agree now, what people generically call Techflex, PET expandable tubing, is noisy, and the easy way to find clear tubing it to get PET tubing. If you want multifilament nylon, good luck, I have yet to see that in clear.
