I'm looking at Erickson 3-piece couplings, and I'd like to know whether they are built for wet locations by design by being threaded RMC fittings, or if there is a specific requirement for them to be listed this way, just like there is for threadless fittings.
Few (if any) standard RMC couplings indicate on datasheets that they are for wet locations. I've seen a T&B datasheet that indicates 3-piece couplings are rated raintight, and other manufacturers' datasheets omit this information, yet there doesn't seem to be a clear difference in the construction of the part.
The environment in question is a vertical conduit stub on a rooftop, which has "close quarters" that limit the ability to install anything above it by spinning it. If you do install an Erickson on a piece of vertical conduit, what is the best orientation to arrange to drain?
