Can't beat the price!!!

I try to buy several extras every time I plumb a project. You can't beat the price.... and I always seem to need a new brake line or two for someone elses project between mine. Just a few of these in the shop and can time and money from running to the local parts store that charges 3 times as much. But the time savings is the best part. Nothing like having parts on hand when you need them.

Finish wipes off with each bend

After bending 1 line in 3 places, I knew there was a problem and needed to stop. The finish, not that good to start with, kinda matte look, just rubbed right off. Returned all 9 pieces and ordered elsewhere for the same cost. If Speedway 3/16 line was less expensive, then I got what I paid for, but it's not. I'm talking steel vs steel not steel vs stainless steel.

I ordered the random pack because I didn't have a flaring tool. And they all happened to fit almost perfectly. I had about an inch or so on the front and back lines so I was able to make a little bigger radius and turned out fine

They are sold straight and you have to plan your bends and use the proper tool to make smooth bends so measure bends where necessary but since they are steel they bend easily and result in a professional looking perfect fit.
