I bought a set from this place,,,go to product overveiw,,, all they really are is "PEX TUBING" used in the heating industry for radiant floor heat,,, the kit I bought beats the R+G type in that if you do have a fall you can just "flip" them over with the scratched side faceing in,, the R+G"s, their fooked and just buy a new one,, been thinking of making some out of the "Pex" it's 40 USD for, 50ft, then you need some large hose clamps, and last some heat resistant backing to install around the pipe that the pex will then rest on,,,then something that cuts it clean,,,,,,as for the looks ,, I don't mind it at all,,never cared what anyone else thinks anyway,,,purposful,,,and saves 700 bucks on a re-placement end can,,,,
