Stainless tubing bender?

Does Harbor Freight sell a kit that can bend 1/2 stainless?
Need to make a new fuel line, like the look. This stuff has absolutely no give at all .

Nobody in these parts does this may as well go for it. Cheap if I make a mistake.

Thanks

You will need a industrial style bender, it will only be able to bend the 1 diameter. With that said they do make a kit so that you can buy all 3 (1/4, 3/8, & 1/2) but it will be over 600-700. I would buy the one you need.

I bend all my stuff and stainless now and have never looked back.

Re: Stainless tubing bender?

Stainless is nice, but not so much for the casual do-it-yourselfer like me. I'm able to bend the regular stuff with my tools, but not stainless.

I but pre-bent stainless or bend the standard stuff.

Re: Stainless tubing bender?

IMO, you'd better off if you call one of the vendors that sells new lines & have them custom bend you what you need. By the time you invest in the tool & the tubing, then add the frustration of trying to bend it yourself, you'll be way ahead just buying it pre bent.

I learned this the hard way as well, when i swapped my TH350 for a 2004r. had to reverse the lines on the trans, and holy crap, even with the aid of a decent tubing bender, that stuff was murder to massage them just enough to get them switched over. whoever put those lines in, was not a diy-er.

Re: Stainless tubing bender?

Working in the oil fields in west Texas I bent way more 3/8 stainless than I ever wanted to. I can tell you that it's not easy and a good bender is a must. I used a Swagelok bender, it was OK and a little pricey. I've never tried to bend 1/2" tubing but I think it would probably be near impossible to bend by hand.

Re: Stainless tubing bender?

I haven't had much luck bending stainless, but it does look cool. Sorry, this post won't help you find a bender.

But - what I've moved to now is copper-nickel lines. They can polish up quite nicely (not super shiny like stainless but I think it has its own cool look) with some steel wool and are super easy to work with, and getting them to seal is a breeze.

Re: Stainless tubing bender?

I think using stainless on parts like these is a waste.. I use the regular tubing that bends real nice and looks great...

Re: Stainless tubing bender?

I looked at this thread and had a great brain wave: Anneal the tubing in the region to be bent. So, I looked up what it takes to anneal it. Way high temperatures for hours. No way could that work for DIY projects. I see that Earl's has annealed tubing at Jeg's , but only in short lengths. So,,, the question becomes one of finding pre-annealed stainless in the size and length you need. I am no help on this, however.
OK, I have returned. It turns out that annealed tubing is a real thing. Here is a chart showing weight per foot of popular sizes. It looks like the length is 20 feet. I did a search on "annealed stainless steel tubing " and on "annealed 1/2 stainless steel tubing". Your luck may be better than mine.

Re: Stainless tubing bender?

Are you able to flare the ends of the 1/2” stainless tubing? If you must use 1/2” SS, you may find it much easier to accomplish “bends” by using the appropriately sized fittings (90/45 deg, etc) instead of trying to bend the straight sticks. It creates more potential leak points, but much easier than trying to man handle it without an expensive bender.

Re: Stainless tubing bender?

HI
Try copper nickle or CoNk . able to be used for brakes and fuel . 1/2 is a little more uncommon .

Stainless to hard to work

Original factory lines had a ""Terne Coating "" Lead based with a small amount of zinc

Bundy tube or the brake line sold today is Zinc coated /dipped for a very short time . It has very LOW corrosion resistance

The Swagelok Tube Bender makes it look pretty easy:

Re: Stainless tubing bender?

I ordered my 1/2" stainless fuel line from Right Stuff Detailing.

Bending 3/8" line was really hard, I'm assuming 1/2" stainless would be damn near impossible to bend with a handheld tube bender.

Re: Stainless tubing bender?

FWIW, I did stainless brake lines with the elcheapo plier type tool from Harbor Fright where you just hold it then pull the tubing with your hand to make the bend. Nothing to it, easy-peezy.

Here's another video with a Swagelok type bender. In this one, they state that they're bending stainless. 3/8" looks easy, 1/2" can't be more than a little bit harder.
