It maintains the bonding integrity comparable to couplings. But it is not clear whether it is also as liquid or gas tight as conventional tapered thread couplings. (The non-threaded part which holds the coupling to the pipe section that it came with.)

I have not personally used it, but it seems installation would be much easier. A lot of the battle with rigid is spinning a bent piece of pipe on to another. These essentially have a three piece on one end. Seems like it would be easier to install

It looks like it would also free you from the plumber's nightmare of having to disassemble the system from the far end to undo a joint in the middle.
(Of course you might just cut it....)

I wonder if you can reuse the spinning piece on the end if you cut and re-thread that side of the conduit. I bet not, there must be some sort of shoulder that it spins against.

Yeah, it looks like you either use it full length or you cut and field thread the end opposite the spinner, leaving you with a "scrap" section that will just have conventional threads at both ends after you thread the cut end.

Easy to install in tight spaces is a big plus. Not worth the money in wide open industrial installs.(it used to run 5 to 10% above GRS in material cost)

I tried it once a long time ago, and we had issues with the coupling coming apart. (that is the free spinning coupling came off the pipe ) That was when the product first came out. The manufacturer says that the coupling connection to the pipe has been redesigned, but I have never tried it after that first time.

I don't see conduit couplings as being liquid or gas tight. Conduit couplings have straight threads and they leak. Only the threads on the conduit itself have tapered threads.

Standard pipe couplings have tapered threads, and I would not have expected female-female couplings for rigid to have straight threads either Among them) other things it would not even provide good mechanical strength.
I know that adapters for EMT have straight threads since they are intended to be used with nuts.
