In particular, Can you smash two different flare fittings together? I have an adapter that goes 3/8-24 "standard flare" male to m10x1.0 bubbles flare, female. The metric Side needs to be inverted flare.

Side question- is a "standard" flare just a single flare?

No.

Side question- No. Double flare.

Let me get this right- The 3/8 is a double flare, male on the line, into a female adapter. Other end is a male end on the adapter, female bubble flare fitting on the line? Or vice versa? The lines are regular old 3/16 and 5mm?

I think you would be way farther ahead to use either metric or standard, and reflare one of the lines to match. Cut off the metric bubble, get a 3/16 nut and double flare the line.

Oh, and yes I have a brake line flaring tool, but it's the el cheapo 7 piece flare tool from HF. I have my doubts about flaring lines (the tool's and my own ability).

This is why I like to do things via adapters. It's all reversible, I don't have to flare, cut, and potentially destroy any brake lines, nor do I need to bend any line.

Flaring lines isn't that difficult. It's all about the prep - a square cut with a bit of a bevel on it.

I guess I should just tell people what I'm trying to accomplish.

The Toyota (m10x1.0 inverted flares) needs an adjustable prop valve. There isn't anything available in that thread and that flare. So I can get a willwood unit in m10 bubble flare. Or adapt to the 3/8-24. Which will involve cutting, flaring, bending, etc.

Does nobody make an inexpensive, metric, adjustable ABPV for Japanese compacts? I see Pegasus does but they want you to buy seperate adapter fittings, which puts me right into the same boat for more money. Looking to keep this under 100$.

Parts store should have a brass adapter fitting, no? I got them for putting sae 3/16 line into a wrx combination valve at advance.

Metric 10x1.0 inverted flare to NPT is a surprisingly difficult adapter to find. We have to have ours custom-made, I've never come across one in the wild. The SAE version is everywhere.

In reply to patgizz:

I been all over the Internet for this. And the parts stores. Sadly, nearly all the staff can't even begin to comprehend the incredibleness I'm trying to achieve.

Hey Keith, placed my order. Thanks again man. You literally solved like 3 days of Internet scouring.

I'd love to know what your search terms were so I can make our stuff easier to find. Glad I could help.

Typed "m10x1.0 inverted flare to 3/8-24" and added on the end for each search the words "coupler/adapter/proportioning valve" also tried "metric adjustable brake proportioning valve", "Toyota adjustable brake proportioning valve", and, finally, I resorted to simplifying the search terms to things like "m10 proportioning valve" or "import wilwood valve". Even "m10 to 1/8" npt fitting". various forum threads would come up, apperently the Honda guys have this same issue.

Side question answer: No, single flares are not acceptable for braking systems (neither are compression fittings, while we're on that matter), the inverted/double flare is a two step process.

Gotcha, thanks. I never considered M10. I'll make it easier to find.
