I used 1-5/8" x 1/8" wall polycarbonate tubing.
It will handle high temperatures, high pressure, and UV qualities are listed as "good", whatever that means.

Just in case the prolonged clamping combined with heat, would eventually deform the ends at the connections, I put stainless steel inserts inside each coupling.
I just took some 1-3/8" stainless tubing and cut a ton of 1/2 inch sections, and painstakingly deburred each one inside and out. Then I pushed them into the tubes.
I read on a few different sites that you can join the tubing with fittings and cement. Well, no, I could never find fittings. So that was out.
Here's a tip (tongue in cheek) for anyone wanting to do anything like this. Get a standard size! I went to the plastic place and asked for 1-1/2" tubing. They said all they had in stock was 1-5/8". I figured that was close enough, and bought it. Well, those little silicone couplers sure as heck don't come in 1-5/8" sizes, but yes, it was close enough. Then I ordered all of those nice clamps just a little too small. I had to bend the T-bolt on each one, and cut down the little area where the clamping nut seats, just to get the bolt through enough to put the nut on. Now they might leak, and I'll have to reorder 10 clamps that are the right size. I bought the tubing over a year ago. I could have just ordered the 1-1/2" stuff and waited for it, and saved a ton of problems. Haste makes waste.
