[RE-wrenches] Exterior conduit in corrosive environments

[Andrew Truitt]

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?

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...

"Don't get me wrong: I love nuclear energy! It's just that I prefer fusion
to fission. And it just so happens that there's an enormous fusion reactor
safely banked a few million miles from us. It delivers more than we could
ever use in just about 8 minutes. And it's wireless!"
