Default confusion on AN fittings for big oil cooler

I just purchased a 19 row oil cooler for my 951 rebuild. It has almost twice the capacity of the factory cooler, at 112 cubic inches vs 67 for stock. The factory lines and cooler were trashed and are long gone, so this will replace it. With the stock lines and cooler deleted and this in place, it should raise my oil capacity to ~8 quarts. The unit is set up for -10AN lines.

The factory fittings on the oil console were 26mm female, I already removed them. I keep hearing people say 22mm as I've done my research, but that doesnt seem to be the case on my car.

So I guess I'll need 2x 22mm female to -10AN adapters. Also it looks like one will need to be 45* and the other 90*. Any ideas where I can find such strange fittings?

I'm also interested in hearing about alternatives such as Earl's braided nylon, ect.

Trying to keep the cost of both the return and feed lines together with the fittings @ under 150 bucks.

Are you sure you measured them correctly? all the threads are M22 x 1.5

AN is overpriced...get JIC (steel, almost identical to AN) instead for much much less money.
go to a local hydraulic shop, out there in oil-land there should be plenty such places, they can hook you up super cheap.

my HD-rubber oil cooler hoses, probably 10ft in all, including fittings, etc cost about $150.

AN and JIC are 2 different fittings. both have different sealing angles.

This is correct, JIC is 37 IIRC and AN is 45.

Also I'm an idiot, what else is new.

The lines are 26mm on the hose side, but 22mm on the block side. Duh.

Nope!!
https://en.wikipedia.org/wiki/JIC_fitting
https://en.wikipedia.org/wiki/AN_thread

Both are 37 degree...the key difference is thread shape.
I don't remember which, but one can thread into the other OK, but not the other way around.

to summarize...http://www.pirate4x4.com/forum/shop-...-fittings.html
SAE and JIC 37* flare are identical, there is no such thing as a JIC 45* flare, however, there is such a thing as a SAE 45* flare. The SAE 45* is used in low pressure applications such as plumbing and LGP or NPG installation.

Both JIC and -AN fittings are 37* flare seat angles. -AN is often incorrectly assumed to be the aluminum version of a JIC fitting, but in all actuality, -AN can be made from as many or more alloys than the garden variety JIC. Technically the fittings should not be interchanged, however, the only difference between -AN and JIC is the thread class. -AN is a military/aerospace spec fitting, with a tighter thread class (but still the same size and pitch as JIC) and is mostly intended for space shuttles and air planes. JIC was standardized to be a less costly High Pressure fitting that has no requirements of keeping a space shuttle in the atmosphere.

The fact of the matter is, that you would be extremely unlikely to find a actual -AN fitting for sale in any motorsport's catalog, or online web store. Most of the stuff marketed as AN whatever thingamajigger is actually just an anodized aluminum JIC fitting. Any true -AN fitting will be listed in it's catalog as conforming to mil spec MIL-F-5509.

I just bought everything I need guys. 10 feet of SS hose, 4 swivel hose ends, and 2x 22mm to 10AN adapters for ~110 bucks. I'll probably have left over hose, but it was cheap compared to the fittings.

At my work we are connecting 37 degree JIC fittings to AN fittings on a test bench for an air system.

It works for what we are doing. Low pressure 65 psi
