Ok...so still begs the question what inexpensive tool would flare 37° stainless tubing that anyone here would recommend?

My nomenclature was derived from my experience with gas lines... and I'm a redneck

Use a 45 degree tool. It will seal fine.

.035 wall? I haven’t run into a hand tool (cheap) that will flare either seamed or seamless that thick.

Ferrules

Yeah need to learn how to spell

Compression fittings, like the Swagelok brand, use one or two-piece ferrules behind the nut that "bite" into the tubing.

The ones we used were not like that..
Not sure of the name, I'll have to ask my hydraulic guys they have them...

What size? I've flared lots of 1/4-.035 with a standard 45 degree flare tool. I clamp it in a vice to improve the hold on the tubing.

The least expensive tool that I find works reliably on stainless tubing are the vise block with flaring pin style. A good quality bench vise is required. Hydraulics supply houses usually stock them.

I saw that on YouTube. I never thought of using a tool that way.

I guess if you have thousands of 1/4 and 3/8 swagelok fittings and a $4500 flaring tool available, you don’t need to beat a hand tool with a hammer or set it in a vice. I’m lucky that way.

What is "Dudesesses"? Is that a female dude?

Do we know who created this interesting document other than someone in the northeastern US?

I have a 45° flaring tool, but it's meant for copper. I don't think that will work? It does do heavy duty K copper, but I've never tried SS.

I've used one on steel brake line, it worked but I wouldn't want to make a habit of it. The unit Akimbo linked probably would have been easier.

Mine are the simple clamp together kind. I have a full stock of 1/4 fittings and have used it for a lot of connections. frogman62 told me he believes the 45 deg flare seals better. I don't know, but it seals fine.
