It's a PTFE hose that has a black nylon outer over a stainless steel braid with a PTFE core (I believe that is teflon?). Car Craft said it would last "for the life of your ride". Also said it would cure the gas smell in the garage.
I know from experience that if my car has been sitting around for 1 year plus, I can count on replacing most of the braided / rubber core lines. One time it looked like the fire sprinklers in a building went off!

Yes PTFE= Teflon
Some manufacturers flaunt it as being something new. Its been around forever in industrial applications. Aeroquip has had it for as long as I can remember in their industrial line. You could probably pick some up at your local hydraulics shop. Just tell them you are after Teflon steel braid and they will probably be able to help you
It is far superior to synthetic rubber hose. Has incredible chemical and heat resistance. I think the #8 I use is rated at 800psi at 600 degrees. It’s smaller OD and lighter than rubber braided hose of the same ID. It has lots of advantages the only disadvantage that comes to mind is that it is not as flexible as rubber braided hoses. (Minimum bend radius is much larger than with a rubber hose)
You can buy the industrial hose at most hydraulics places but you will not be able to get pretty anodized fittings or the hose you mentioned with the black cover unless you buy from an automotive line.
FYI I’ve had the same PTFE lines in my car for 6+ years with no issues.
