First time I've posted since the "great HAMB divide", so hopefully this is in the right place. Please move this if this goes somewhere else. I'm running standard coated 3/16" line (non Stainless Steel). I need to use 90-degree bulkhead fittings to mount through a bracket on the body. Everything in the system is standard double flare fittings and nuts with a mix of a few pipe threads. I seem to be having a hard time finding 90-degree bulkhead fittings that are intended for a 45-degree double flare type connection. I see all kinds of bulkhead fittings, but these seem to all be AN 37-degree flare type fittings. Only other thing I see are 90-degree fittings in 45-degree SAE style that use SAE conical nuts. Am I missing something? Does anyone make a right-angle bulkhead fitting for use with 45-degree double flare and nut? I keep finding stuff like this... http://secure.ch***isshop.com/partdetail/963303/ Is there anything out there like this for standard double flare? What about br*** SAE with nuts? Are they intended for use in brake systems? Used them in fuel systems, but never thought to consider them for brakes? SAE type fitting and nuts... (not just for copper and good to 1900 psi plus) Am I doomed to using 37-degree fittings and buying a 37-degree flare tools? Thoughts? Input? I really don't want to use a bunch of adapter fittings to make this happen. There must be a simple solution! Clue me in! Thanks guys!
I just looked thru the Godman Hi-Performance catalog and don't see a 90 degree, 45 degree fitting, in fact I don't even see an adaptor from AN to 45 degree flare. I would call Godman, 800-456-2369, they might be able to help.
Never found any either; ended up using an 1/8" NPT br*** bulkhead with 1/8" NPT x inverted flare adapters on both sides.
Ok, so I'm not blind at least. Ha! Was thinking about using NPT bulkheads. I'll consider that. My thru-frame fitting is basically that as well. Just hate the added adapters. Posted using a record player and an Apple IIe
Hear you on the extra fittings, doing two cars now with under dash master cylinders and I think we will just run the steel lines thru grommets to avoid that.
Yep! That's my reason for needing them as well. Clutch and brake masters are under the dash. Such a pain... Posted using a record player and an Apple IIe
How about some British car flare nuts on that 90 fitting they make them in female out of steel then you can double flare the line. Look at Fedhill for some fittings.
Just looked in my Edelman book. You may try a PN 146320 OR Weatherhead PN 46x3. That is a female connector that "may" have enough thread for a thin jambnut acting like a bulkhead fitting. If it works it would be clean and sano. Just an idea, I have not tried this.
Thanks man! I'll check those out! I'm definitely up for a little fitting mod if it will get the job done and look half way decent too.
Hey Scott I had the same problem so I just used a regular br*** 90* fitting and machined a cover to go over it.
Since my fittings will basically be hidden, I could ALSO get away with this. Did you use a NPT to NPT elbow, or is that a internal flare to internal flare elbow?
HAHA good question I don't remember off the top of my head. I will have to take a look and let you know.
Best that you are going to be able to do is use an 1/8 bulkhead fitting with 90 degree pipe to inverted flare fittings. I've never seen an inverted thread bulkhead. I do show that in my catalog.
Thanks everyone for your input! It's appreciated! Going to just use a standard IF to NPT elbow and an adapter and call it a day. I'll make a little bracket for each fitting and treat them like bulkhead fittings. On a tangent... What do you guys use on NPT threads, if anything? I've heard some people say nothing, let the fitting work as it's supposed to, and others say to use a sealer of some kind that won't contaminate the system. What's the good word on this?

I learned to use anti seize from an ol boy that plumbed B52s and SR71s and did all of our hot rods Posted using the Full Custom H.A.M.B. App!
I've had success in making bulkhead fittings out of inverted flare br*** coupling nuts and some thin sheet br*** from a hobby shop. I drill appropriate size holes and file them to the hex size of the coupler and silver solder them together. I used 3 of them on one piece of br*** to p*** the 2 brake lines and clutch line through the firewall in my track roadster. I attached the new bulkhead fitting to the firewall using nutserts and 10-32 s/s ****on heads. Charlie
I also ran into this problem. You would think some manufacturer would offer a part so many people would like to use. I finally gave up and used AN fittings on my setup.
Anti-seize! Great! Thanks for the tip! Great idea! I like that! Right?! Or maybe it's a sign to just not use them. HAHA!
I use liquid teflon. Also on the bulk head fittings, if they're going to be hidden I used some that were pipe thread on the inside. Kinda bulky but you can run any fitting into them. 908284 edelman
Thanks man! Good info! Just ordered a bunch of fittings. Going to try elbows and adapters. May switch them for the NPT bulkhead though.
These are the double flare fittings I used to through the fire wall. They have a retainer nut then the fitting that follows tightens behind to hold the flared tube. The inside of the fire wall looks much the same, but without the retainer nut. Very neat and tidy. Posted using the Full Custom H.A.M.B. App!
Oh!! Those are nice! So where do I find them and the nuts?? What is the inside connection? Posted using a record player and an Apple IIe
They are male threads both ends of the fitting to accept a double flared tube. There is a hex on the inside of the bulkhead so it can be held while tightening the retainer nut on the outside. I have a washer both sides to spread the load somewhat. I looked up the part number BH302 but that will probably only be a local shop number. There is no branding on the item and nothing listed on the invoice. I could make a call and see where they come from if you wish. Posted using a stick in the sand on a windy day in June!
I have noticed the same issue with fittings being AN-03 style male on one end and 1/8 NPT on the other. Just like everyone else I found it very strange that none of them were available in a 45 SAE style fitting. The through frame fittings I suppose would generally be hard line from the pipe side and flex from the AN side, so I guess it makes some amount of sense why these are that way. I did find this do***ent from BrakeQuip online that states you can use a 37 deg. seat with a 45 deg. flare, just not the other way around? I have never heard of this, but it would explain the complete lack of 45 deg. fittings. Have a look on pages 21-24. http://www.brakequip.com/wp-content/uploads/how-to-plumb-your-street-rod.pdf Anyone ever heard of this?? It seems like a no no, but BrakeQuip is a pretty large and reputable name in auto brakes so if they put their name on it....... I guess its legitimate?
There is a business down here that produces straight through S/S DOT legal bulkhead fitting to suit 3/16" line with 45 degree male ends either side. I bought a few for my project. Will post photos tonight.
