I have never run across this before.
Details would be appreciated.

It's called a bushing.

I never looked at it in that way. I haven't encountered a bushing that fits 100% inside a pipe before. Plus it looks like it is all one piece. I was pretty hung up on those two things and never even thought of a bushing.
