I think they are just standard pre-made copper line sets (copper tubing,
flared ends with flared nuts and overall insulation) that happen to be
sold by a company named "pexsupply"

Those lines seem to be for mini-split systems. Found this in the FAQ.

Q: What is the tubing material? What is the minimum bend radius of the
line?

A: The tubing is made out of level-wound copper. The minimum bend
radius is not a listed spec. We would estimate that it would be about
7 times the outside diameter of the copper.
