I don't know, I charge it back to my department and sneek it out with me. I'll see if can find out some specs on the stuff. Its a thick wall silicone tubing. 3/8" id and 1/2" od...Originally Posted by trance565

The only trouble me and Rockhammer have with the stuff, is that liquid must evaporate through the tubing walls at a very low rate (like < 1 ounce a month or 1 cc/day). Rockhammer says after 6 months or so that the rate will drop to about half that much. its weird, you don't perceive any loss through the tubing walls, but at such a very low rate, you wouldn't anyway. The stuff does stay very flexible even after long periods in time. Rockhammer does say it'll stain with what ever dye you use in the system after some time, but it doesn't really matter if you never change colors.
