There are compression fittings listed for wet location but the standard compression fittings cannot be used in wet areas.

I don't think threaded rigid couplings are listed for that use. Threaded rigid couplings leak a lot more than the old EMT compression couplings that we can no longer use in wet locations. Conduits in wet locations are required to be "arranged to drain". I don't see a real world issue if the couplings leak.If not so listed then no they cannot be used.

We use to use standard emt compression couplings outside because we were unaware that there was a product listed as rain-tite.
Why bother with compression when you can go set screw...

I don't think there was in the past...it is my understanding that UL changed the listing standard.
The OP is talking about compression type for RMC conduit not EMT.
I don't think the RMC compression fittings are rated for wet location as the EMT fittings are.

Would you consider rain tight/concrete tight to be the same as wet location rated? If so American fittings has plenty of options through PLATT https://www.platt.com/platt-electri...Fittings-Corp/NT2761/product.aspx?zpid=823924

Interesting issue - never considered this. I found these: Raintight SSR series by Eaton.

Here are a few selections from the description:
only appear to be made for sizes 1/2 thru 2"

I believe RAIN TIGHT is as wet location rated as your going to get with conduit fittings.

American Fittings fittings (just had to get that in there
) contradict Eaton/Cooper's claim about the only line. Perhaps they mean the only line of their making. Just can't trust advertising anymore... even though it's not like we ever really could... just feels better to say it.
