EZ bend...copper alloy...compression fittings. Not that I’m crazy about compression fittings for brake lines. IIRC steel lines are good for 16k psi. Copper and compression around half that or less.
However if PA lets the lower psi pass it must be ok. PA is hell on inspections, sometimes for the silliest stuff.
Can’t you just buy an over-length steel line and add bends/loops to use up the extra length?
