I'm not sure about the tape, I'd guess the poly tape would start to come apart pretty quickly and then the crows would start picking at the foam. I believe the rubitex holds up better against the UV, but you'll want to check that. On another note. Pex and even Pex-Al-Pex aren't rated for the high water temperatures any sort of glazed solar collector is going to generate, flat plate or evacuated tube. It may work for awhile, but eventually you'll have the pex blow out right at the connections to the collector. Some people try to get away with a few feet of copper right at the connections, but I generally think it's a bad idea. When your collector flashes to steam for whatever reason that steam expands and takes up a lot of volume and will transfer all of that heat to the pex. You really should use copper or there is flexible stainless steel lines that are available. The flexible stainless steel is essentially natural gas flex pipe, but sometimes a bit different steel.
I used the foam insulation for the straight runs of the A/C piping. The tape is used at the joints of the foam and at the irregular piping surfaces – valving. Taping the entire run after covering in foam was not done but probably would not hurt as long as one did not crush the foam insulation. The foam has built in adhesive at its mating edge.
The foam, the pipe insulation, and this Poly Tape will all so the same thing. The tape can be used outdoors in temperatures down to -35 °F. It is waterproof and UV resistant.
This tape is not designed for direct contact with PEX. We would recommend that you sleeve the exposed PEX with PVC.
