I am searching for a supplier of Convoluted Copper Tubing that will sell in
lengths of 250' or less (preferably 100' or less). Convoluted copper
looks like this: http://www.packless.com/desuper/supertube2.jpg (but
without the black insulation). I have already contacted Packless (the
company from that URL) and they do not sell lengths of convoluted
copper, it is just used in the products they make. It is typically
used in heat transfer applications like heating/cooling for buildings.
The one place that does sell it is morebeer.com and they charge $109
for 25'. I want to find out what it costs from the actual suppliers or
some sort of wholesaler.

Funny! I am looking for the same thing. I will keep an eye on the post
to see what you come up with. Good luck.
