Flaring Question
 

When making hard lines for a N20 setup, can you use a brake flare tool?

I think they are differing angles, 37 vs 45, but not sure.

AN fittings are 37deg flare, so if that is what you are plumbing the system with then you would probably be best picking up a 37deg tool. Jegs/Summit sell them pretty cheap. I think you can use a 45deg tool if you are in a jam, but I'd pick up or borrow the proper tool. Flaring can be difficult enough.

could you use brass fittings instead on the n2o lines and use a 45 degree flare or can you only use the aluminum fittings with a 37 degree flare/chance it with a 45?

edit:


basically, there is a 45 degree brake flaring tool at hand. can it be used to make hard lines to replace the flex hose on the n2o plate setup in OP's car or are we hurting ourselves?

thanks 8-)

I haven't plumbed an NOS setup before, so I don't know the answer to the first part. But beyond looks, the AN stuff is better suited to come apart and go together lots of times without seal degredation.

I know people who have used a 45 deg flare tool in conjunction with the AN fittings/tube sleeves and tube nuts with success. I don't think its recommended, but it can work if the flares are good. The tube sleeve ends up taking up the difference.

Slide the tube nut over the line, then the tube sleeve, then flare the line and if the flare is good, it should seal. But I would still prefer to see the proper flare tool used.

thanks for that info, cleared some stuff up great.

Are you planning on using stainless hard lines? Flaring stainless can be more difficult so you may need to stick with the proper flare angle to hope for a proper fit.

That's a good point, all the flaring I've done is with regular steel line, NOT stainless. I don't think you'd have much success trying to flare stainless line with a typical store bought tool or like the one in the link I posted above. To get good consistent flares on stainless you would probably need a hydraulic flaring tool.

Yea, the sweetBMXr has a fancy hydraulic flaring tool I believe. And I am kinda sure the lines are not SS, they are some EZ brake line or similar.

yeah its the mastercool hydraulic flaring tool. best thing you could ever buy IMO. saves your hands and they make a 37 degree cone!

Absolutely. You can flare stainless with a cheap tool but you will probably waste a fair amount of tubing. The tubing can frequently push out of the tool, and then you usually have to start over. Not that I've ever been there :D

Honestly I wouldn't screw around trying to force a seal with the wrong angle. If it's important enough to need a flare it's important enough to have a good seal.

Wait, now it does do both? :?:

As per chat last night, he said he would have to buy the flare cone that has the different angle on it for $50-$60.

Yea, he is confusing me. :|

at least someone knows wtf is going on. yeah matt i'll have to get a 37 degree cone. so the whole thing is possible, just not at the moment.

Alright, thats what I figured. And that 37 die would be useless for ya pretty much right?

I'll bring the intake and what not down before the meet and we can mess with it.

well i could use it to mess around with. i'll try to see if i can get just the cone since all the other stuff was repetitive.

Alright, lemme know.

anyone know where to get like a kit or bulk order of b nuts and sleeves? kinda like a brake line fitting kit idea.

try mcmaster-carr, they might. or speedway motors.

looks like it. 3/16" line is 1/4" outer diameter if i measure correctly. just not sure if the thread is correct. no bulk either.

that site is insane though!

probably just better off going nitro dave's

Any idea what size nuts I need?

I think they are differing sizes I recall... prob should take a look this weekend and then order some.

The easy way to check is to see what size wrench you use on the hose ends
7/16= 3AN
9/16= 4AN
11/16= 6AN

If you know roughly what length you will need, NAPA now carries an amazing assortment of pre-flared straight hardlines in various sizes that you can bend up yourself. They might be the brake line flare angle though, I never looked close enough other than how many different pieces they had.

At Autozone they are. Double flared 45*.

Yea, the idea is to use Adam's flaring tool and buy some of his fancy brake lines and try to save some money. We shall see.
