Making oil line using factory oil line for its fittings?

[911pcars]

For one thing, copper work-hardens and will eventually crack. I forget the second reason; maybe something to do with copper reacting with lube oil? (don't quote me).

You could make the lines out of brass, that's what the factory lines are made of, then silver solder the fittings onto the brass tubes.

yeah brass is good, but copper is real easy to bend, brass very hard. Do you mean that the copper brazing cracks, or the pipe?

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?

I don't sell AN adapters, per-se. I sell solutions that eliminate the need for adapters.

If your cooler is a "Modern" setrab or mocal, I have Widemouth fittings that thread directly into the cooler to provide native 30mm metric male connections. These are not an-metric adapters, these are native fittings for the application that I machine. Hence none of the flow restriction issues associated with AN-12 fittings and adapters.

I say "Modern" because older setrabs had welded on fittings instead of the modern ones with threaded fittings.

My solutions let you build an oil cooling system with high-flow 30mm fittings throughout even with setrab/mocal coolers, just like god and the factory intended.

Copper pipe work-hardens, gets brittle, then cracks. Brazing uses brass or bronze filler rod to join materials together below their melting point.

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?).

Say what!! A while back, a gasoline line failed. I called to get a new part and they wanted $65. I took the failed part to my local hose shop, they cut off the german crimp and hose and replaced it with a SAE hose and new crimp. Cost? $7.00.

Find a shop that wants to work with you.
