Technical Trans Cooler Line, Quick Question

Starting at a C4 running to a Walker radiator. Planning 5/16 steel line from the ****** to alongside the oil pan to near the front of the engine. From the engine to the front crossmember area I was going to use this line:

and AN fittings. Would then adapt that to the radiator.

Anyone use this line for ****** coolers? Want nice fittings, not hose clamps. Trying to do things right and once.

Thanks,

I personally use 5/16" "steel fuel line" I buy from my parts house. I make the lines from coat hangers or welding rod first to get the bends right. I've used a HF bender but I have a better one also. The radiator came with flare fittings all ready in it and I've got a double flare tool.

 

Nope, never used it. Probably wouldn't for Trans lines either at almost $9.00 a foot.
I am going to keep it in mind in the right size for power steering lines though, thanks!

For Trans line I always use hard line and inverted flair fittings.
If I needs a section of rubber ill bubble the hard line and use the squeeze band clamps with the correct auto Trans cooler hose. Looks way better than fuel injection clamps or worm clamps. But the rubber is just a short piece like an OEM line.

 

Yes, I've used 6AN PTFE/SS from a different manufacturer and it goes to together nice and tidy. I'm always
impressed with Fragola, its at least equal if not better compared to Aeroquip or Earls. 6AN is probably
over kill for a C4 especially PTFE lined, but its what I ended up with on my C4's

 

I have the 5/16 steel double flare line and a nice flaring tool (Eastwood) and benders (several to choose from), can make any line I need. That's no problem.

My radiator and the ****** both have 1/8"NPT so I realize the -6 line is a little big but there's nothing between that and -4. Would rather have a 3/8" line there than a 1/4". Flex line will only be about 9" long.

I also have an AOD in my '62 unibody that I have to build lines for too. Wanting to do both the same so I only keep one set of parts for spare stuff. Think the black PTFE line and black fittings will disappear well and serve the purpose.

Cost isn't an issue. Going to do it once and do it right. With 2 setups to do, it just makes it easier.

Jimmy six has the right idea. The OE's used steel line for years. The only problem was rust.
I ran mine in one piece from the trans to the rad, put enough bends that it can flex, and don't tie it down too tight. Mine have been fine for the last three years.
