Is this oem?

TrailBeast, I am a criminal. Long ago when a rusted tube twisted off on my 69 Dart at a front wheel cylinder, I "fixed her" by installing a section of tube w/ brass compression fittings. The cheap plumbing type w/ 1 brass ferrule instead of better Swagelock. Car was stolen much later, so can only dream it failed when the thief was running from cops. They did arrest a guy in a stolen Jetta w/ my license tag 7 yrs later.
