exactly the opposite of this needed - this is male-male. I need female-female.


Trying to adapt the OEM GMT800 hydroboost pressure line to the -6AN adapter on the Crown Vic steering rack. Trying to use all the OEM lines for the HB install

I can't find female m18x1.5 to female -6 AN , seems like it doesn't exist. anyone know where to get one?

I could cobble it together putting a -6AN female to -6AN female in the middle of available adapters, but I don't love that



next option is take the line over to NAPA and have them convert it to -6AN. Hoping that's not too $$ if I have to

last option is buy the adapter to go into the HB/Pump unit instead and buy a -6AN to -6AN line rated for the power steering pressure.


this guy was doing the same thing and gave up. Hydroboost hose to a rack and pinion ... hose to -6AN fitting? - The 1947 - Present Chevrolet & GMC Truck Message Board Network
 
I guess 3rd option wouldn't be so bad.
Could use the adapters above with this line or equivalent, it says it's rated at 1500PSI and I'm reading the pump operations in the 250-750PSI range. but I still may need to add another adapter in between to put a 90* for routing purposes.

Really just trying to minimize the amount of joints, AKA potential leak points

this may be the way to go, then go to NAPA if it fails. I think I have a 37* flare tool kicking around

Absolutely not this

Just get 2 AN6 adapters on the box and HB and make a regular AN6 pressure line.
X2
That's what I do when I do a 2.0 swap. Fitting on the box, Fitting on the pump and a new -6 line.

Just get 2 AN6 adapters on the box, adapt from AN/JIC to NPT and run an off the shelf NPT hydraulic hose you can find sitting on a store shelf anywhere in the country.
Fixed. Race car consumables do not go on daily drivers unless you want the eventual joy of adapting to something else in a parking lot.

Not sure if this is the correct metric side, but a possibility.

ETA: Oops. just noticed you wanted female to female. sorry.

ETA 2: Here is a female -6 JIC union to stack with the above to get you to a female to female adapter.

Might need to do 2 fittings, female metric to male JIC then a gender change JIC.

Helps if you don't look for "AN". Hydraulic fittings are JIC.


Like this...
Would just need pipe to JIC which is a common fitting or hose end.

My bad for not specifying. I agree with Arse. A new -6 crimped Hydraulic* line. I don't play around with the build-a-bear fittings.
 
thanks everyone for the hunting. seems like the only adapter solution is stack them, which I'd like to avoid

95% chance I am going to take the OEM line to NAPA. Going to call and see if they have a -6AN/JIC fitting.

If not I'll order a fitting and ask them nicely to flare it, I have a 45* flare but I don't think I have a 37*. need to hunt my garage

Nothing a baggy of field serviceable -6 fittings and a length of hydro hose couldn't fix in a parking lot real quick.
 
Yea, another vote for adapting to -6AN and making a line. Any hydraulic shop or tractor dealer (case, deere, etc) can make a replacement line in a pinch (and/or have one ready to go on the shelf), after all a -6AN is just 3/8JIC, super common place on equipment. And yes, I have used a hose from John Deere on a racecar when in a bind :laughing:
 
I was trying to do something with M18 thread for engine oil lines at work.

What I found with the hose/fittings suppliers is they mainly carry metric adapters to get to NPT, and carry on from there. I ended up with a male M18 to 3/8" npt (female).

Besides that, look at cutting up and welding fittings. Sometimes brass fittings with enough bulk can be shaped/drilled/threaded into custom fittings. (Obviously not the best for high pressure tho).
 
I need to swing by NAPA. the OEM line will reach and I already have it. Pretty sure I can just cut off the end, put these on, flare it with a 37* flare, and call it a day. $1 at a hydraulic shop. $8-12 on ebay/Amazon.

I'd need 2 adapters to keep the line original. Have decided I'd rather modify the line than have stacked adapters, though I have no doubt that'd work fine as well.

closure:

i said screw the OEM line, ordered the adapters, and am going to have a 6AN / 3/8JIC line made up. I have found a bunch for $50ish but I need 2 90* ends not 1.

with 2 90deg fittings you have to make sure your clocking is correct.
I suggest using a 90deg adapter fitting on one end (PN 6500-06-06):

Save an adapter/leak point and find someone to make you a hose with swivel 90 hose ends. Not much more money and saves headaches.

good point. I wasn't thinking about "clocking" in terms of the twist of teh hose. that probably explains why they sell it with just the 1 90*

This was my backup plan. now it's my primary :cool2:
 
Those ends won't hold to HP requirements.
Phone up BMRS with your hose dims and they will have you a quality hose by tomorrow with crimp on AN6 90* swivel ends, with options of Goodridge heat sleeve, raychem cover, etc. It will be a reasonable price and you won't have to worry about it for the next 15 years.





Better? :flipoff2:
 
Did you try Brennan industries, hydraulic fitings,

A straight on one end avoids the need to clock anything but creates a space issue. If you are putting 2 90 degree fittings they have to be oriented perfectly.
