Just make sure the tube has a smooth glossy finish. I would be careful of EK ZMT tubing. Its good but also really bad for those that might want to tinker or change the loop.

This stuff makes compression fittings bite so well that once you screw them tight, you will probably have to cut the hose to remove them later. If you plan to make the loop and then leave it untouched, then go for it.
