Installing receptacles in a process area, a lot like a kitchen. They like the looks of cast threaded FS boxes with covered receptacles/and switches.I want to use EMT box connectors as well as some LFMC connectors. I would not be using it for EG I am running a EGC I know the FS box is NPT and my fittings are NPS

I use bell boxes with ss device covers, and emt steel compression fittings, for surface wiring where looks are important. The ss covers are a plus

I know many of us have done exactly this for decades, myself included. But is not a compliant installation due to the EMT connectors not being approved to install into a hub. I think only recently there are EMT connectors made with tapered threads for this purpose. Bet if you ask your supplier for these you get a dear in the headlight look.

I would think the interface between a connector and a box hub wouldn't matter if it's not being used for water-tightness.

The OP was proposing using emt connectors with FS boxes.,,I get what you are saying about straight threads into hubs. I did a search and found an emt connector listed for hubs. It’s not well known among electricians or inspectors.

That is what I pointed out in post #4 is that they are now EMT connectors for this purpose. My personal opinion is that this much ado about nothing but the code is what it is. This reminds me of the the big deal made some years back about compression EMT fittings not being water tight and the manufacturers responded with listed "rain tight EMT connectors", which are now common place.

Especially when the inside of the conduit is still considered a wet location, regardless of the listed fittings!
