William, We are also in the market for a good non-corrosive solution for coastal locations. We just finished a job with aluminum EMT with threaded couplings and it worked fine, but that job happened to have a simple DC conduit run. I can imagine things getting a lot more difficult when trying to thread bent conduit into a complex wall-mounted run. Are there really no rain-tight aluminum compression fittings in existence?
My electrician advocates using PVC in these environments. My arguments against that are 1) aesthetics and 2) durability of the joints considering temperature degradation of the glue and thermal cycling of the material. What do you [all] think? Andrew Truitt Standard Solar Inc. p.s. - I sent something out on Expansion Fittings yesterday but it never showed up in my inbox, though I did get one response to it that was addressed just to me. Did anyone else get that one? Very strange...
