I have a few electrical conduits I need to run below grade using those
gray colored PVC conduits (Carlson brand).

I have been connecting those pipes together using regular plumbing PVC
primer and glue. You know the purple primer and the general purpose
PVC cement you use for PVC drains. I just noticed today in the
electrical aisle there is a "specially formulated cement for Carlson
PVC conduits" and the instructions did not mention primer. So I am
wondering, did I make a mistake in using general PVC drain pipe
cement? Is using primer a bad thing in this case?

Second question is about connecting this to EMT pipes. I ran the PVC
pipe below grade and then used a 90 degree elbow to come up to the
inside of an exterior wall. I glued a PVC female threaded coupler to
that and then screw in to that female adapter a male threaded EMT
connector, then on to the EMT pipes. Everything looks good and then I
realized the 1/2" female adaptor and threaded coupler are actually
more than 1/2" deep, and all the furring strips on the inside of this
exterior wall are 1/2" deep furring strips, and now with these
couplers they protrude more than 1/2", how would I lay sheet rock over
this? or do I need to punch a big hole in the exterior wall and then
work in a couple of offset pipes to offset the thicker connectors into
the wall cavity?

Thanks,

MC

If the cement holds there just isn't a problem. Conduit doesn't have to be
watertight. The wires in conduit should be rated to function in either wet
or dry conduit.

Just make a hold in the sheet rock or put up two sheets adjacent to the
conduit. When everything else is in place just plaster over where the
conduit is. If it's more than 1" thick in places, you can build up the
plaster 1/8" without anyone being the wiser. Beyond that you might see a
slight "hump." You might consider putting some fiberglass tape over the
"joint" and taper it out over 10" or so,

*Supposedly some glues have a primer in them. Don't worry you should be
fine.

*Shave the back of the drywall. There is a drywall file or rasp for this.
You could also notch it and then tape over it later.
