Technical Brake line/hose fitting question

Had hoses custom made for my speedster build. They’re all for 3/16” tube. They all have the SAE inverted 45 degree fixed female that will be clipped to a steel brkt designed to secure the hose to the ch***is. The other end has has a female flare swivel nut. The issue is that I need to connect the female flare swivel nut end to a br*** tee (inverted flare). From what I can tell, no such fitting exists to connect the two based on what I found. Hoping someone has an idea as to how to solve this dilemma.

 

Your only hope is to find an adapter that screws into the inverted flare and leaves you a male SAE flare. I doubt you will find it. The hoses should have inverted flare ends.... but I'm sure you've figured that out by now.

 

I think so. Haha! Seems I’ll have to cut off the the end in question and have them crimp on another inverted flare end.

 

How about a Jic T with male ends ?
To me you are looking for a Jic/ A&N
# 3 or 4 male to a inverted .
1/4 I believe thread . ?
The fitting does exist.
Look to Aviation, Aerospace , beverages & other out side of
Automotive, most like Summit ,Jegs only have a small Selection of what the brands below actually carry.
Jic = steel /Br***/ SS
A&N = typical aluminum

Brands "Master Catalogue's""
Check E, R , A brand's only make certain fittings that others do not make
So you will have different brands
Earls
Russel
Aeroquip has "3 different" fitting catalogs
Not all 3 bands make same fittings .

Your local hydraulic hose and fitting Can make what you want D.O.T line / house
If you do not want just the fitting to adapt If you do not have a hydraulic crimper press.

 

I have a Fairview (Canadian) catalogue which I downloaded. Couldn’t find anything, but Summit might have a fitting, however they are mostly AN (37 degree). I need 45 degree. I find all this stuff really confusing, and back in the day, I used to look after the pneumatic system on the Light Armoured Vehicle (LAV), but that was 30 plus yrs ago. Lol!

 

I would double check to make sure your female swivel ends are in fact SAE 45 degree and not AN or JIC 37 degree. The main difference between AN and JIC is the AN fittings have a tighter tolerance on thread fit. I mentioned to double check is that many of that style of hose use AN fittings.

 

@Ziggster
One of the 3 company's I posted make the fitting ,
I m sure thoe its Earl's or Russel ,
I am thinking Russel & its steel or
S.S fitting.
It seem each company has a pat #
So there some fitting Not made by others ,
You will find if you look in there master.
I think Eaton has 4 different catalogues.

To me I feel its getting harder to find thing's / item on Internet because the search keys off every word not specifically what you're looking for I wish there was a option for specific description look up .

 

Using these Boolean search "operators" may help you to narrow down or expand your internet search results. Different search engines may use similar but different methods and processes.

Your photo appears to show AN ends. Did you contact your supplier and ask what they actually put on there?

 

I’ll double check with them, but from my understanding, AN are typically a speciality type fitting not used commercially in vehicles. Could it be a JIC, maybe since they are a hydraulics shop. Didn’t know the real difference between JIC and AN, so thanks for pointing that out. My Speedway backing plates came with an AN male and I brought it with me so they made sure to match it. These ones not so sure.

 

Told them to use 45 degree, but like I said in my previously reply, who knows for sure. I have a typical 45 degree Rigid flaring tool and not an AN flaring tool, so wanted to use 45 degree.

 

Damn! Gives me the shivers thinking about algebra. Haha! The problem/solution? today is that Google AI is your first response typically. I tried using it, but I think either I, or it, or both got confused with the terminology. I’m still not sure of the correct terminology honestly, and that’s why I figured I would ask the question here as I can’t be the first to go down this road. Lol!

 

I know, but if it’s a 45 fitting, it won’t work. Not sure why there aren’t any 45 degree ones if that’s what’s used on vehicles, or are they all 37 degree?

 

Sorry, that one I pulled up is actually 37° on both ends.

 

Don't take chances on your brake plumbing. Stopping is way more important than going!

 

For sure. I won’t be taking any chances. Will ensure I know if fittings are 37 or 45 degree. I went with customs hoses to ensure I was getting quality vs. some Chinesium stuff off of Amazon for like 1/10th the price. My four hoses were just under CAN$100 ea.

 

As to hoses and fittings used, there are lots of braided hoses made for off road use that use AN as their standard fitting since racing uses AN almost exclusively. And those hoses are not DOT certified. If you bought your hoses from a vendor that makes DOT certified hoses everything SHOULD be all SAE 45 drgree. But as Ronald Reagan said, trust but verify !

 

Interesting. This was kind of the feeling I was getting as far as AN was concerned. Curious as to why folks use AN if they’re not DOT approved. The adapted fitting that comes with the loaded Speedway backing plates I purchased are AN.

 

@Ziggster

I am sure the hose with fitting is
Jic / A&N tapper ,
Use a sharpie .
Make & test with fitting & look @ seat marking .

A&N was originally Army Navy
& also stand for & reference for Aluminum fitting,

then later
commercial Jic same tapper ,
Jic used as reference for fitting
Made of Steel , Br***, S.S

In last few years there is Companies
that have change the Reference of Jic
to another reference , I ran into this a few years ago the New reference
I believe it was Eaton & Parker .

Dot hose I think all have a transparent cover Sleave over the steel braided hose
& comes Clear & other colors
& are marked DOT in ink
& fitting crimped .& extra crimps .

 

I have another issue with the handbrake cylinder I purchased off of Amazon. It’s a Wilwood knock-off, and there are no specs/details given for the two ports. It seems the actual Wilwood comes with an adapter fitting for the outlet, but even Wilwood doesn’t give the specs.
I think I need this fitting for the outlet. The outlet has 3/8” - 24 female threads with a female flare.



Outlet port: 3/8” - 24 Female Flare for 3/16 tube.


I bought these tube nuts off of Amazon, and they just literally arrived a few minutes ago. I figured I could use the 7/16” - 24 tube nut on the inlet to the cylinder, but I just tried it and it won’t fit. It must be 7/16” - 20 then which is the “standard” 7/16” thread pitch for inverted flare. What a total cluster!



Inlet Port: 7/16” - 20 Inverted flare for 3/16 tube.

 

Found this which is somewhat helpful.

 

So, based on the fact that the 7/16” tube fitting I bought as part of that pack is 7/16” - 24, which matches the thread pitch for SAE inverted flare. This means if the inlet is then 7/16” - 20, then it’s a JIC style flare.

 

I’m using 3/16” tube, but this style of fitting is likely what I need for inlet of the handbrake cylinder.

 

This will fit the inlet to the handbrake cylinder, but gives me a male AN -3 (3/16 tube). Means I now need an AN flaring tool.

 

I have found off brand cheap so called br*** & aluminum fittings are under cut of threads , radius not correct & less material thicknesses crack
Including off shelf AutoZone , Avance
if not @ least Dorman ,same with brake tub stick 's .
There is so many items being sold
Amazon , Flea Bay & ext that are not what they appear you need to look @ all specs & description just wast of $ & your time.
Things are not like 25 yrs ago

 

Just a point of clarification. AN fittings are not necessarily DOT prohibited. It's the fact that the majority of hoses you find Army-Navy fittings on are intended for applications where DOT approval isn't required so the vendor doesn't get their product certified. Hoses being sold for on road applications are SUPPOSED to be DOT certified and stamped as such.

 

Steve,
I used AN stuff everywhere on my build to avoid this exact problem. Granted, I had to get a 37* flaring tool too but in the long run it saved me a ton of misery and aggravation.

I researched and found that only CL***IC TUBE and GOODRIDGE sell readily available DOT certified stainless braided brake hoses at a reasonable price.

I got mine from CL***IC TUBE through SUMMIT. You can tell the DOT certified lines from CL***IC TUBE by the red band on the hoses.

Through CL***IC directly (they're in Lancaster NY near Buffalo) I was even able to special order a custom made 70" length DOT certified hose.

I understand that a stainless braided hose may not be the look you want but you can always cover the hose with low temp black shrink tube from the local electronics supply or order the black rubber hoses from CL***IC as they're available too.
Cheers!

Thanks Marc. Might need to borrow your flaring tool. The tech at the hydraulic shop where I just had my hoses re-crimped and he said for automotive brake systems, the 37 degree and 45 degree flare will seal adequately if you interchange them. Not so sure about that. Haha! Still chasing down that one br*** fitting. Dropped by Grainger, and I’ve bought br*** Fairview through them before, but Fairview is using a Weatherhead P/N and they said it didn’t come up in their system, but it shows up on NAPA’s website. So, will be dropping by NAPA shortly.

 

Look at a place that sells plumbing supplies. They seem to use a lot of inverted flare stuff that is kind of backward from automotive applications
