Steel and Aluminum -AN together??

[96Turbo]

I just finished ordering everything i need to put together my high pressure line for the power steering system. However, after looking at my invoice, i noticed that the adapters (metric to an) i purchased are aluminum. I got steel hose ends since they should handle the pressure a little better.

Is it ok to use steel hose ends on aluminum adapters?? Seems like everything would be fine since the threads are the same....but will the different metal composition have any bad effects? I'm just thinking about the different heating/expansion characteristics of aluminum and steel

[burnsauto]

As long as crush washers are used, I dont see any problems you'd have as far as using those two metals.

give it a shot...if it leaks, you'll have two options..
•screw power steering
•fix.

well, upon further research i might have really fucked up ordering the adapters. in this thread: earls gangster power steering (http://www.zilvia.net/f/showthread.php?t=169550), he uses one o ring fitting (on the rack), and one non-o ring fitting (on the pump). And both fittings i ordered don't have o-rings.

Note: this is for an RB25....and on a how to from racebread.com the guy used two o ring fittings. Should i just return what i got and get two steel o ring fittings?

How is the sealing mechanism different for pump and rack?

[RyanWheeler]

I'm going to be using the o-ring fitting for the rack and the regular fitting for the pump. I believe this is the way it was done on the "earls gangster p/s" page that I've seen pop up a few times.

Edit: this is on an s13 red top, not sure if the p/s pump is different or not

[96Turbo]

i'm thinking the reason you're not using the o ring fitting on the SR is cuz it has that banjo fitting that comes off the pump into a threaded section. Whereas with the rb, it doesn't have this fitting so i'm threading it straight into the top (where there would be a banjo fitting). I still dont' see how this is any different than where the adapter goes into the pump though

EDIT: here is the page with exactly what i'm trying to do. I just noticed that this guy is using steel hose ends with alum adapters. So basically my new question is: do i hafta use the o ring fittings?? Or can i get by without and using crush washers? i'd like to avoid returning what i bought.....summit rapes you on shipping charges. http://forums.racebread.com/index.php?topic=1568.0

one fitting is crush washer the other is Oring'd

aluminum and steel is fine.

[96Turbo]

but the crush washer would only be sufficient if i were using this, right??

I'm attempting to put the adapter straight into the pump like below:

Would that require an o-ring as well?? If so then i'll need two new adapters :(

[96Turbo]

anyone have any insight?? I'm thinking i'll just hafta reorder two o ring adapters. If anyone is interested, i'll be putting these up for sale:

-6 is too small for power steering, i'd go at least -8 or -10, just my .02

it's cool that you went with earl's fittings tho. i rarely see anyone doing that (ppl are too cheap), them shits are expensive though.

nice rb btw

I'm using -6 for my high pressure line. Seen several others with the same size. I'm using the earl's power steering hose and fittings (the blue nylon looking hose)

[Z U L8R]

;/ , i dun like that hose.....steal braided ftw.....

[96Turbo]

i got the russel powerflex hose which is designed to withstand high pressure. That combined with steel (vs. aluminum) hose ends makes for a very strong line. The russel hose is a little cheaper than earl's and it's standard steel braided without the fabric cover thingy. You don't need a large hose for the PS line from what i've read because the stock line becomes very restricted by the rack, so even though the stock line appears to be pretty large, the I.D. is actually quite small.

SO!! Is to consensus that i need an o-ring adapter on the rack, and an o-ring adapter into the pump? I didn't know you could just put in a -AN adapter into an outlet that was designed for a banjo fitting...but that's exactly what's shown on the RB above. (Z U L8R, that's not my RB...but soon you'll see my build thread ;))

The stock line has an ID smaller than a -4 AN line - no reason to go any bigger really.


As for a steel onto an aluminum AN fitting - it will seal fine, but it will tend to eat up the face of the aluminum male fitting, and potentially can make it more "pointed" at the end and hard to seal. So don't excessively over tighten the fittings.

[Z U L8R]

in my defense, i was looking at the "suction/feed hose" from the resivoir to the pump, so that's what i was referring to. the high pressure side -6 is fine, sorry for the mix up. my fault

[96Turbo]

it's cool. no need for the bling bling braided line for the return hoses. I'll probably just get some new OEM power steering hose for that. 3/8" if i remember correctly.

I've decided to exchange the adapters i got for Earl's adapters with o-rings. I'll let you guys know how it all works out in my build thread in a couple months.

[xsparc]

What i did was use the o-ring on the rack side, i tried to put an o-ring one on the pump but it didnt fir, the pump port isnt deep enough, so i had to use a regular AN fitting.

-6 seems kinda small, my pump and rack are now making a funny sound when im turning the wheel. almost like its being starved of fluid. but with small and slow movements there is no sound... odd.

[96Turbo]

so you put the adapter straight into the pump?? Like in the pic of that RB above? Or do you have an SR with the banjo fitting with threads on the end??

[xsparc]

i have a KA, but mine is set up like the SR. It seemed to fit better like that. and i didnt need to use a crush washer, sealed tight with no leaks.

[96Turbo]

so....you mean you used that banjo adapter thingy from an SR?? On my KA (single cam) there were no threads on the fitting...it went straight into a rubber line

[xsparc]

Im not sure what to call it, but yea, i have the little extender thing on the pump like the SR. There used to be an banjo bolt in there but the non o-ring AN adaptor works fine.

I couldnt get the little extender pipe off but it looks like another banjo bolt so i would assume it would work out the same way.

But you never know, it is a nissan.

[let5l1de]

& sr, ka (e) and ka (de) are all different however i believe they are all interchangeable providing you retain the inner valve in any case. banjo is a correct term.
