Stainless tubing questsion

[EFI69Cam]

Looking for 3/8 stainless tubing that can be formed with the mastercool flare tool into the GM quick disconnect end.

The tool works perfectly with parts store steel tubing, but I'l like to use stainless.

Go to a local supplier of stainless tubing, buy a foot and see how it goes. I don't see what you are asking here.

You need seamless, thin walled annealed. You're not likely to find that at a local supplier.

This is where I get my stainless for plumbing.

I did that with a piece I had around and spent a couple hours getting the piece out of the forming die. It got wedged in there. I think the wall is too thick.

Thanks! Your right, I'm not going to find that locally.

This stuff is .008 thinner than what jegs sells and a little cheaper, and its the same grade.

I would not use it. At $40 for 25 feet, I would be willing to bet it's not the same quality. It doesn't really state that it's seamless fully annealed. Plus, it's coiled. So, you're going to have to straighten it first, risking work hardening it before you even start. Stainless is difficult enough.

Have you tried McMaster Carr?

[wmhjr]

Mcmaster doesn't sell thin enough wall. Thinnest is .028. Do yourself a favor and just get it from a reputable place like the link I provided. The wrong material will destroy the dies in the master cool kit. I know this from experience. For the small amount you need and for the infrequent purchases, take advantage of others experience and get the correct stuff from a vendor who supplies performance car builders as their job.

I don't know about the master cool kit, but I've always used .035 wall material (1/4" to 5/8") SS from McMaster-Carr. It works fine with my Imperial AN flaring tool. If you can get thinner material elsewhere, that's great too.

[andrewb70]

Look on page 126 of the Mcmaster catalog.

Don't have access at the moment. Is it fully annealed (not soft annealed) seamless straight and less tha. .020 wall? In any case I'd rather know for sure. Stainless is just a pain to begin with.

I've seen .035 damage the dies with the tool. I've replaced my 3/16 die once.

When you get home you can check it out and enlighten us.

Looked at it and still have questions. They do have .020 wall 3/16" stainless however it's shown as "soft annealed" rather than "full annealed". My impression that "soft annealed" was really "process annealed" and not "fully annealed". For "annealed" it does seem as though the thinnest wall is .028. I don't know if McMaster is being accurate in their description. I've been told that fully annealed is what we should be using. I also don't know what the impact is between them. Again, that's why I chose to avoid the drama and just get known good tubing in order to try and minimize risk.

Mc Master lists very specific specifications, including a Rockwell hardness rating. My point is that there are options. I am sure that "what we should be using" is not that unique.

Andrew, I'm not disputing that McMaster provides some amount of data, nor am I disputing that the product there will or will not work. I don't know. Again, I find stainless to be a real PITA to deal with in terms of flaring - especially in high pressure lines with double flares on critical safety systems such as brakes. That's why I choose to and recommend eliminating the drama and risk and just buy from a known source of materials that are known to be correct. The McMaster pricing is actually more expensive than the source I posted as well.

For the record, the Mastercool tool set is not actually designed for stainless, but it works with it assuming you have the right materials and are careful. That being said, all it takes is a single section of the wrong material to ruin one of the die sets. I'm sure there are plenty of places to get this material but in THIS regard it is somewhats unique. I seriously doubt that eBay is one of them but who knows. If you want to pay more, I'm sure McMaster is fine (assuming you're also OK with figuring out whether or not it is the correct stuff).

Guys, he wants to put a "rib" in the tubing for a gm quick connect fuel line, that's the way I read it anyways. So like andrew said try it but I don't think it will work real well.

.035" seamless stainless tubing from McMaster is fine for a 37 degree AN flare, do it all the time....it does not need to be annealed for this style flare but MUST be seamless.

I have never tried to 45 degree double flare any stainless tubing but it can be done as wmhjr says with the right tubing. This will absolutely need to be annealed because stainless work hardens so fast, so the only way to double flare it is by starting with softest you possibly can.

I called them today and got .028 wall annealed seamless. Hopefully it won't get stuck in the die.
