Another Brake fitting question

I just got my Tight fit master cylinder fittings from Total Performance. They have 4 AN fittings for output. I thought I would be smart and order two 12 of brake line with the proper AN fittings. I was going to cut of the AN fitting on one end and replace it with a standard 45 double flare male fitting.
The problem is the two 12 stick of line is Stainless and I cannot flair them.

Now I guess I need to find a 4 AN female to standard female.

Any suggestions? This brake stuff just confuses me.

take it to a place that makes hydrolic hoses, they should have the machine to produce the 45* double flare on the other end.

If they dont they may be able to fix you up with an adapter.

Hi Shawn,
You should not double flair SS line, it will harden
& split, unless you use annealed SS, + SS uses 37* flairs. There is a ton of info on SS lines here, just
click on the search button on the top of the page & type in SS brake lines.
Good luck,
Rich

37* flares are only used on AN (stands for Army Navy) and JIC fittings.


If you have flaring tool like this


You "can" do a single flare with one of these....I have done it, but its not easy. But I haven't hurt the tool or myself yet.

However sense I have access to a tube and hose machine now I usually flare stainless on 45* double flared.

I have had single flares crack but have yet to have trouble out of a double flare.

WARNING to double flare ss tube you MUST have a machine or take it to someone how has a machine and the knowledge to do it.

I do have a piece like that.
I tried to do a single flair with it last night. It stripped down the little
teeth enough that it will not hold my standard metal tubing anymore.
The tube slip when I try to do the first phase of the double flair.

yup...that'll happen with some of the cheaper one (and some of the good ones) plus its almost impossible to produce a double flare with one of those tools in SS.

Your best bet is going to a shop that makes hydralic lines and let them use the machine to do it.

As was stated before, the SS tube MUST be annealed to double flare @45*, it does not matter if you use a machine or not.

Call the company that sold you the tube and ask if it is soft annealed or regular stainless tube. If it chewed up your flareing tool trying to single flare it, it is probably un annealed.


If it is regular stainless tube, you must use 37* flares and fittings. JIC will interchange with A-N when using hard lines.

There are many adapter fittings available from Earls, Russel, Goodridge, and Aeroquip.


Later, mikey

Yeah when we do SS on the tube and hose machine we have to heat it with a torch then produce the flare then heat till its HOT HOT then let it cool.

all it really does is lets the crystals in the metal to reform in the shape of the flare.

Like I said to get it done right take it to someone who makes their living making lines.

Once you get it to a 45* flare it'll connect to all of your existing lines.
