Making oil line using factory oil line for its fittings?

[ChrisBennet]

I can't seem to find it now but someone on the list mentioned that you could use a short factory oil line as a source for 2 metric fittings. I've talked to a couple of places that can crimp hose (NAPA and someplace like NAPA) and they didn't see how it could be done.
thanks,
Chris

Chris, if the original lines were crimped then I would think the new lines could be cripmed also.

I have my hose work done at a local shop that caters to the industrial crowd. They seem to have a much wider range of stock materials than your run of the mill NAPA or lesser hose shop. Several of the other local hose shops referred me there when I was looking for suitable metric fittings.

I may have chopped the info

Warren says...
I keep telling people that you don't need any of those $50 adapters if you just get one of those $25 short front (OEM factory) flex hoses from the brass factory lines to the radiator-style cooler. Two 30 mm metric fittings that, if you cut off the swaged crimp rings, will slip perfectly into AN-16 hose. Get the metric ends swaged at a local industrial hydraulic supply ... and you save an AN-16 fitting AND the adapter! If you already have a 29-tube brass cooler or Carrera cooler ... you don't even need to buy the hose! Inner Flexible Oil Hose from Front Oil Cooler to Supply Line, 911/911 Turbo (1984-89) H-207-111-00 $25.00

Thanks Ronin! I don't care what the guys say, you're OK.

I went to the hose place at lunch and got an education.

Apparently, once upon a time you could get could get hoses made up like RoninLB says. Some places may still have the old Gates crimpon band/sleeve thingies.
Nowadays, lawyers and insurance has gotten involved and the new less error prone fittings have the crimped part as part of the fitting, not separate. Hose shops aren't allowed to reuse the hose or the fittings for liability reasons.
According to the guy I spoke to, the problem with the old type of crimps was user error. As many as 1 in 3 would be bad he said.

Also, seeing the Japanese tractors and bucket loaders out front I thought "Ah, I bet they have metric fittings!". No dice, the Germans use DIN fitting and the Japanese use something else (JIS?).

Chris,

Go to the industrial hose guys in your town. Waco has one that made me up all new hoses using their own fittings that worked wonderfully on the Porsche. Entire set of hoses for about $65.00. But that price is from memory, I am not at home with the receipt...

There is an industrial hose shop in the next town. I will try them next.

The hose failure thing is ridiculous. a) any imbicile can crimp a hose with 5 minutes of training b) typical crimp ratings are over 1000 psi, versus your low pressure oil c) 1 in 3 failures? b.s. d) they aren't exactly impossible to test.

Send me a PM if you want to UPS them to me and I will do them for free. (far fewer lawyers up here).

He meant that 1 in 3 fail to crimp right so you have to do it over. Thanks for the offer. I'll keep looking locally before I impose on anyone.

Sorry to highjack this thread, but does anyone know the type of metal tube that runs from the Bottom of the block, over the heat exchanger, and in the bottom of the oil tank. I might make one and I was wondering what type of tube to use. You guys seem to be up on your oil line knowledge.

"...."Ah, I bet they have metric fittings!". No dice, the Germans use DIN fitting and the Japanese use something else (JIS?)."

DIN is metric, so the German tractor/earth moving pik-a-part boneyard is open game.

"...but does anyone know the type of metal tube that runs from the Bottom of the block, over the heat exchanger, and in the bottom of the oil tank."

It's just steel, and plated so it doesn't rust quickly. Thinking of fabbing something in lieu of the somewhat expensive factory line? Sure. Why not? But take a look in the usual used parts sources for a $20-30 or so version first (that's just a guess).

I have been looking for a used one to no avail. If you guys find one I'll take it. Thanks

Aside from Porsche, I can't think of any German tractor makers. I've never even heard of a tractor/earth moving pik-a-part place, never mind a German one. Man, I've got to get out more.

Ok, so my front mount oil cooler has -12 AN lines coming out of it, stopping at the Carrera cooler anxiously awaiting my willingness to plunk down the cash for the 30mm to -12AN adapters. This thread states that -16AN will fit perfectly to the 30mm hose. Any way to make the 30mm fit to the -12AN or do I have to 1) buy the adapters or 2) run -16AN from the 30mm hose then buy a much less expensive -16AN to -12AN adapter?

[911pcars]

Pegasus Racing as does Elephant Racing, I believe, sell 30mm -> -12AN adapters. You can also try AJUSA in San Diego.

I was going to PM this to Colby because I don't want to start up the whole "shouldn't use AN12" thing, and I'm sure some poeple are going to frown on this solution. I will check back after a few hundred miles to say how it works out:

Colby, I just hooked up a Setrab center mounted front cooler using AN12. I did Warren's trick of cutting up a Carrera cooler short oil line to get the two 30mm fittings, and I found that the AN12 hose does indeed fit on the nipples of the 30mm fittings.

The catch is that I used AEROQUIP SOCKETLESS hose, which does not have a steel braid. I don't know what stage your project is in but this solution worked out great (and cheaply!) for me.

[Colby]

I'm aware of the Pegasus adapters...for nearly $100!

I am also well versed on the frowns on -12AN. But I got a great deal on a used Setrab and know many ppl who use -12AN w/ no problems. If I notice problems w/ pressure and/or cooling, I'll do what I have to and bump up to -16AN.

So in summary... Take one short hose going to my cooler, cut off the ends. There is an inner barb or something that will slide into my -12AN hose. Then have someone recrimp to my hose...correct?

God, maybe I should just quit being cheap and pay the $100 for the adapters...

[Britwrench]

Stoddards sell all the OEM Cohline fitting and crimp sleeves. Be aware that you will need a shop with the correct crimping dies to make the hose.

[Mukilteo911]

here is a weird one. The trombone cooler lines are brass right ? Is there any reason I could not make my own cooler lines and cooler out of copper ? or does copper react with the moble one oil ? It just seems to me that copper is cheap and brazing on ends is easy and since it is low pressure why not. Can anyone find a good reason not to?
