Technical steel fuel line question ???

Does anyone if there is a place that sells a tool to form the ends on steel fuel lines like the one pictured? It makes for a nice non-slip connection when the rubber hoses are connected. Thanks for any info here.

You can get a formation that does the same thing but doesn't look exactly like that. Use a standard flare tool, set it up for a double flair and stop befor the first step is finished.

There's a tool they sell that rides the inside of the pipe and makes a outie ridge but it ****s

 

i have actually done something like that by sticking a philips screw driver in the end and twisting. once the tip is in wiggle it around a little.

 

That's what she said!

 

Google tube beading tool.

 

Yep ! ^^^
That's the one that ****s

 

Correct. What you end up with is a metric "bubble" flare that works very well with hose.

 

Use the flaring tool and bulge the end just a little. You don't need to bear down all the way.

 

There are hydronic flaring kits that make the posh lock connecters and they are close.
I think Eastwood sells one, I got mine from the Snap -On tool man.

 

I have used a farrel type union connection before. Place the nut and farrel on the line. Tighten nut to union, loosen and then hack saw off the nut. Leaving the farrel as a stop so the hose with a clamp will not pull off .

 

$400.00.
Then the jiffy ***e dies are an add on

 

A friend of mine (airplane enthusiast) has a tool set that has different sized mandrels that go into the tube and you roll the tool around like a tubing cutter, increasing pressure a little at a time, to raise the bead. I made myself a die that slips over the tube, with a chamfer to match the chamfer on my flaring tool. I leave about 1/16" clearance between the two parts and squeeze it with the flaring tool. Works pretty good.

How about some photos?

 

Here is the tube end of the die with a 3/8, flat bottomed hole and the chamfer. Next is the other side of the die with a 90*countersink for the flaring tool. Next is set up to use. Next is compressing the tube. Last is the finished tube end. This is aluminum fuel line because I didn't have a s**** of steel. The steel actually comes out a little better because the clamp doesn't crush the tube as much.

mastercool is the MFG of the tool its cheaper to buy it from a supply house .

 

thats the ****** , I picked my whole set plus A-N dies for $400 had to shop around .http://www.toolpan.com/Mastercool-7...dftrk=gdfV27228_a_7c824_a_7c2023_a_7cMAS71475

 

Here is another tool I've made for large tube for splicing radiator hoses. It's just simple dies welded to a pair of locking pliers. I just lay out a line and go around the tube a couple of times, moving about an 1/8" at a time. The s**** of tube I used here is 16 ga exhaust tubing.

I've got an old Kent-Moore AN flaring tool set that goes from 3/16 to 5/8 and it has a beading die for each size. I love these old tools.

 

This a great idea, along with the post by blue49. Thanks for posting.
