Autozone's breakline tube is painted sort of OD. a little darker shade than 23070. I used it to make all my lines.

Got them installed. Not that hard. Messed up on one flare that had to be redone. I think the hardest part was just making the smaller bends.
I use the same stuff as you Ken from AZ. Pretty cool how its almost a match on the paint color.
Cost:
25' brake line $19.99
fittings 3 packs of 5 $ 8.97

Ok, so what is a double flare?

Brian

get a spring that just fits over the pipe and bend away, it can still crimp if you go too hard or fast but it usually works well.

A double flare is where the end of the tube is folded back on the inside of the flare. Requires a slightly different tool than single flares. Plenty of info on double flares on the Internet - a search engine is your friend.

Most automotive brake and fuel lines are required to be double flared. You can find the proper flaring tool for double flares from reasonable to a couple hundred dollars. They also come in both SAE 45 Deg and Aviation 37 Deg.


Step one a die is used to create the shape shown. Step two is the normal flare but results in two layers of tubing in the flares load bearing surface when it is seated on the receiving side cone.


A little better illustration here. Note steps go vertically 1, 2, 3, 4, 5, 6 and not straight across the illustration.

Here's a tool for under $30

This is the 37 degree tool I have for aircraft work. It sells today for $689


This is my 45 degree automotive tool. $150

Well this certainly is not the cheap way to go---but after messing with cheap hand flaring tools that only seem to produce good flares every three attempts I bit the bullet and got one of these

Actually the deciding factor was needing lines for my 2004 gmc one ton diesel (if you own a gm truck/vehicle crawl under and look at your lines--scary after 6 years)

Anyway got this thing to do the lines--I cannot say enough good things about it. Its not cheap but these things can be Really expensive. Biggest issue is everyone wants to borrow it

I use CuproNickle or Cunifer (UK) brake line...much easier to flare and bend and doesn't rust up here in the North. It costs more than steel (about 1.75x)...but I hate replacing brake lines.

FWIW, my 71' XJ6 Jag has Cunifer lines on it from new...they are still good with very little corrosion.

Yowza, that certainly isn't the cheap way, but I can see how you got there. I tried a Lisle brand tool first and was unhappy with the results, so I returned it and got an OTC 4503 which worked for me. I've been real happy with all the OTC tools I've bought so far.

A source for Cunifer line in the US is http://www.cunifer.com/ - their website says "exclusive importer".

I have one of the Eastwood tools also, works great on all the sizes I need to flare...

And I got my Nickel Copper Lines from NAPA ask for NiCopp lines... Costs more but are the proper color and seem easy to work with.

I admit I have not made any lines yet... waiting for the temps to drop...

Amen on the temperature. Been hovering right at 100 here for a couple of weeks, with not much of a break in sight.

Laying on my back under that oak tree working on the brakes is for the young!

The nice thing about Okla vs. Texas Hill Country is usually once it hits 100, it's not far to the first cold front. Ok, it gets hot still, but one can see fall coming down the road.
