The 1" PVC is the only thing that would fit in that side entrance (and you can barely get a locknut/bushing on it). The FMC, frankly I had it leftover, along with the fittings. I could have spent more $ and used PVC sweeps/elbows, etc, but its such a short distance, it would almost be "elbow to elbow" (its like 16" or less of FMC).
I can't tell from the picture (too low of resolution), but how'd you do the transition from FMC fitting to PVC? Did you just glue it into a coupling, or was it a special transition connector? Normally, I'd have to use a box to do that transition.
