I'm replacing a very long line that goes from the master to the LR. The original was one continuous piece, over 120 inches. This means I'll have to use at least three pre-flared sections, as the longest available is 51 inches.
I was never very good at using a flaring tool, plus the OEM fittings are bubble flared anyway, so that kind of canceled my option of just replacing the corroded portion of the line. I'll still probably end up having to use a thread adapter or two. The master port has metric threads, and the flex hose inlet is 3/8-24 if I'm not mistaken.
Now my question: How do the two different materials compare as far as ease of bending? Also, is the PVF coating durable enough to withstand scratching during the fitting/istallation process? Does it last indefinately or eventually erode from age, like paint? I know the NiCopp is supposed to never rust, but it is more costly & hard to find in bubble flared.
I did use a piece of NiCopp to replace my left front on the same car, three years ago. I found it not quite as easy to bend/shape as was advertised.

Looking at the various pieces on Oreilly and Advance websites is a bit bewildering, since they have so many combinations of pipe size/thread size/flare type, and I have to factor in my starting point and end point have the two different thread sizes.

Sorry for the long post but I'm trying to eliminate the Q/A back & forth as much as possible.
This is for my daily driver FWD LeSabre, and I'm on a budget.
