custom hoses/hydraulics

Can anyone recommend a good custom hose place?

During my trans swap I have found out that the clutch slave flex line has too many threads on the male end that threads into the slave cylinder.

It could also be 1" longer for easier installation so I'm leading to having a hose made then possibly upgrade to stainless from rubber etc and etc.

Anyone got any suggestions? I don't want to cram a bunch of washers since I'm this far down the rabbit hole and the main goal of this project is do it right, do it once.

Where are you located? What kind of male fitting are you having trouble with? Is it its pipe thread, flare, inverted flare, bubble fitting, or a banjo fitting?

A good industrial hydraulic hose shop could probably help you out, the trick is to find one willing to do automotive work, and that doesn't charge crazy price for it when they do.

A lot of NAPAs around here can do it.

Look for an Oil Filter Service in the area or a place that sell Parker fittings as they can usually rebuild your existing hose or make up an entirely new one.

Anywhere that does agricultural or industrial hydraulic hoses.....most have about any fitting you can imagine and custom make their hoses.

Do you know all the specs you need? I could make one at work if we stock all the bulk parts.

I use an industrial hose and coupler shop down the street. They will make exactly what i need in a few minutes. Not a bargain, but not ridiculous.

It works out to be the same price as ordering a hose from summit or jegs after you factor in shipping, but they make it while I wait. ~$30 for a 6-18" brake or clutch line.

If you have any mills or industry in your area you will have a shop that can do it. Know any millwrights? They will know.

Farm machinery dealers (John Deere) usually make hydraulic hoses.

I live in the Detroit metro area. Should be plenty around I just hate when I go to do stuff around these parts with "them fancy metric non murican tiny ass parts" they tend to throw a fit or don't have the equipment.

I've seen some places near me via googling with parker but haven't looked much into it.

The size is female M10x1 and male m10x1. it is non banjo, maybe pipe thread? but it doesn't looked tapered at all...

I'm interested in this because if this works out I may have oil cooler lines made in the near future instead of spending 250 from racing beat.

Thanks for the input all! I have some direction now :)

When I redid my PS hoses on my VW I used metric to AN adaptors and then used the correct AN hose and hose ends for the job. In my case it was Teflon lined -6 hose (2000 psi) for a system that could make 1100 psi. I was amazed at the different adaptors there are.

It wouldn't be pipe thread. Probably inverted flare or something similar. We don't stock anything like that in metric.

Is there a reason that the male end with too many threads is causing an issue? Since it isn't a banjo or o-ring fitting all sealing is done at the flare end, the threads or flange at top of the threads have nothing to do with sealing.

Look for the NAPA with the pallet of tractor hydraulic fluid out front. Nobody is going to give you E36 M3 over a brake hose, Chevy has been using metric brake hardware long enough they're used to making hoses for ORVs.

In reply to EvanB:

I figure it would just leak. Stock seems to use a copper crush washer. Let me try and snap a pic. I havent even put fluid in it yet.

oh, that's different from the Miata then.

I go to an industrial hydraulic shop (well, the only hydraulic shop in the country) and they cost a bit less than ordering the part you're trying to make. Wish I'd done that with my car's brake lines, the ones I ordered were too damn long.

I use an industrial hydraulic supply joint. They owner also happens to be a racer so he's not too hard the one offs.

This is what i am working with:

That is either the wrong line or the wrong clutch slave. The slave has a flare seat and the male end on the hose is not a flare.

You need something like this.

Flip open your yellow pages phone book, look up either "hose" or "hydraulic". Take offending current hose in hand and ask for one X amount longer.

These shops are everywhere. They have to be, as hoses are used commercially and industrially everywhere.

In reply to EvanB:

I forgot to mention to use the rx8 transmission in the rx7 you can't use the rx8 slave cylinder since it hits the oil filter pedestal. But a 1998 Acura integra GS slave bolts right in! Also its only 15 dollars at the auto parts store. I think the rx8 one is closer to 30.

So yes this is my stock clutch hose on the rx7 matted to the integra slave.

Does the hard line from the rx-7 side have a copper crush washer as well or does it have a flare like the male end of the hose I linked? If it is a flare the Miata line should work if it is long enough. If it has the straight thread and copper washer then you are likely stuck with a custom hose or adapter.

I think I have a spare Miata clutch slave line I could mail you if you want to see if it fits.

In reply to EvanB:

The hard line is a flare male end just like the picture.

I found a hydraulic hose shop near work today I am going to try and get like a 90 degree adapter so I can retain my stock hose for ease of parts replacement/maintenance.

What year Miata is it? Per orelieys auto parts its female/female but both m10x1 http://www.oreillyauto.com/site/c/detail/BHH1/BH380177/01440.oap?year=1993&make=Mazda&model=Miata&vi=5011084&ck=Search_clutch+hose_5011084_3327&keyword=clutch+hose ^ I used 1993 for this one.

Exotic Rubber is the main Parker house in the Detroit area. Pirtek can help but both are trained to jam the counter trade on pricing. When you are desperate they know to knock the profit margin up a bit.

The one I have is off a 91, the hose you linked is only part of it since the factory line goes from soft line into a hard line to the slave that bolts to the transmission. The complete assembly from hard line to slave is female to male (like the picture I linked but with part of it a hard line). I imagine the Miata line linked would work and would be the easy way to do it (I have one on my Miata).
