Your flex has some writing on the outside of it which should

LESSON LEARNED:

The old cable clearly says it's 1/2 inch cable on it, had I only looked!

In hindsight, I was lulled into complacency because I could easily
measure the fat end of the original elbow at an exact 1 inch, so, it
seemed so natural that the conduit was one inch that I didn't doublecheck.

It was only when the one inch box didn't fit, and the 3/4 inch box didn't
fit either, that I took a second look at the problem.

Even then, it's wholly unnatural that both sides of that elbow were
actually 1/2 inch connectors!
