Clearance was a bit tight, was tough to get the sticky fiberglass around the epoxy covered pipe nice and tight.  Ugly job.  Let it cure for the recommended hour, turned the water back on, worked just fine.

There’s a similar compression fitting that would allow transition to pex. Cut out as much of the galvanized as you can. It’s going to leak eventually.
