Brake Line / Flares / Threads

[HYDRODYNAMIC]

I’m running hardline on the links and flexible at the pivot points. Flexible lines are AN female -3 which is 3/8-24 thread.
I can make or buy 3/16 hardline with a bubble flare which looks a lot like the adapter I had originally purchased. The adapter coverts inverted flare to a male AN. Technically bubble flare is 30* but it is a radiused cone and conforms to the 30* seat angle.
Has anyone used bubble flare and AN together?
I’m looking to eliminate extra connections to minimize failure points.

Why not flare the hard line to the 37 deg and use a AN hard line fitting?

That’s one extra fitting. Same as using the adapter I have. It would be nice to eliminate any adapter.

And use tube sleeves under the tube nuts to get them extra snug and don't have to worry about them giving you issues on removal later.
I did this exact setup on my Carryall project and just used AN bulkheads at the ends of the links vs an adapter. Everything AN / JIC where I could.

this is just what i was going to suggest ... go super baller with the eversen setup or just do it with split tube and a tab.

Billet Bulkhead Mounts

These billet bulkhead mounts are perfect for securing brake lines and differential breather lines to chassis tubes and suspension links. Designed to fit around 1.75" or 2" tubes. These brackets feature a 3/8" hole to accommodate a #3 (3/16") bulkhead fitting, and a 3/4" hole for a #8 breather...

The brake line builder at the industrial supplier who also pressure tests all the DOT lines says it will seal. The angles are close and the flaring is not that precise. When tightened up the bubble will form to the AN seat.

so why would you be asking us knuckle heads about it? sounds like someone in the know has the answer you need

I thought about a welded tab and bulkheads but I don’t like how rigid the line is. Right now I am planning on band clamping the crimped section of the hose fitting. This will stress relief the fittings. It also allows some flex or slippage if hit hard rather than a broken or loosened fitting or seal.

Because it’s something a knucklehead would try and prove it works. I doubt the hose builder has ever done it even if he says it will work.

Not the way I'm thinking about it. They make AN fitting that you slide on the hard line then flare it and bolt it to the other end. Same number of parts as a bubble flare deal.

FIFU.

Make it stainless hardline and fittings it's not much more expensive, but lasts forever.


As an example this is the line kit im ordering for one of my square body chevys.

Why not flare the hard line to the 37 deg and use a AN hard line fitting and olive?

Can confirm, buddy of mine is running exactly what your trying to do. He hasn’t had an issue with it.

Isn’t that the same as busted knuckle sells in their brake line kits? That’s what I’m doing on my rig. Flare with a brake flaring tool and bolt them together. Works slick.

See knucklehead approved! I new someone had either driven off a cliff and it’s a bad idea or it actually works.

Band clamp on the hose fitting for stress relief of the fittings.
30” pre made Napa hardline with bubble flares for the 40” links.

 

[chaplinfj60]

is this the flare tool that can be used?

 

[azdirt3.0]

That's the tool I bought and have used to make similar flares to what Hydro was doing above.
