I think you need fittings listed as "raintight" - but I am not sure.
I haven't ever used a compression fitting that wasn't listed as raintight I'm sure they exist but I don't know how many of us use themfor a fitting to be used outside where it is subject to wetness, it must be a raintight fitting and listed as so. NEC requires it. A standard compression fitting is not listed as raintight.
an old bit of info on raintight fittings. Don;t know if it is still applicable.
actually, I can't buy ones that are listed raintight.I haven't ever used a compression fitting that wasn't listed as raintight I'm sure they exist but I don't know how many of us use them
The fittings I use have the plastic piece in them that the regular compression fittings do not. I buy mine from the local IRBY wholesaleractually, I can't buy ones that are listed raintight.
No wholesaler in my area carries them in house that I can find.
I suggest you look closely to be sure your are raintight. They have a seal in them that the non-raintight fittings don't
What is the task your trying to accomplish? Why not PVC if water is an issue? Could you use sealtite if an RMC can't be used?is there a seal that goes w/ emt compression fittings to make it rain tight ? or is no good to use emt where it may be subject to rain
