Which of these braided hoses is right?

HEL rears and clutch hose on mine...no issues but I did notice it and asked the same question.
What was the problem fitting the clutch line? They're usually not too bad.
Goodridge ones are better ;-)
Those dual seat fittings are a compromise, I don't really like them. They'll seal ok but will deform the flare on the brake pipe a bit more than the proper concave or convex fitting.

I agree on the Goodridge (no favouritism obviously 
)
Mark is there a specification for the diameter across the open end of the flare? The one's I've measures go from about 6.7-7.6mm on a 3/16th pipe. The ridge on that edge of that concave Hel is about 6mm the best I can measure it, that leaves 0.35- 0.8mm best case of flare to overlap and seal.

Getting it off the hard pipe on the body. - Once I got it undone it was really easy to change it at the other end and bleed the line.
I've just knocked up a couple of flares and the HEL does butt end to end. The flare isn't wide enough to slip over the end like the Goodridge does.
I also noticed the pipe on the HEL sat slightly offset where as the Goodridge one sat perfectly central.
This is with a softer cunifer pipe, I'm not sure how it will cope with the original steel pipe.

The steel pipe will more than likely end up looking the same. As for sitting offset sometimes that can be down to the flaring tool or because the flare doesn't locate as well on the dual seat fitting its easier to do it up on the piss.
I'll dig out the specs but off the top of my head the o.d of the flare should be around 6.9-7mm and the inside should be no less than the i.d of the tube. Looking at the one you've already done I'd go in a bit more with the 2nd punch, that'll help make it fit the Hel fitting a bit better.

I'll dig out the proper sae spec sheet tomorrow but this is the nearest I could find from a quick google search.

Yeah, I found a copy of that somewhere else last night Mark. Using those figures, the 3/16th double/sae converts to 6.91mm+-.18mm so 6.73 to 7.09mm. So my oversize flare is out of spec and my "small" one is in spec.
George, on my travels around the net this weekend, I've seen similar but says don't use it on brakes at all, a single flare allegedly can't hold the pressure, but on fuel lines it's supposed to be ok.

I wouldn't get too hung up on the od, what's inside is more important ;-)
What did you do in the end? Would be good to know the diameter of the top of the convex part of that fitting.
