Tips on Double Flaring Brake Lines

[Whaler]

Hi guys thanks for the replies.

I work with 1/4, 3/8 and 1/2 in SS tubing in the mill where I am at. So I have bent my share of the stuff.
All my tools are imperial eastman and swagelok This is what we run all our industrial airlines (supply and process signals) to all our pneumatic equipment and process valving in the mill.

Here's the diff...for instrumentation the flare is 37.5 deg. not 45, as in automotive applications.

I looked at a few different flaring tools today they ranged from $45 to $130 CDN. Rigid made the expensive better quality one.

What I am hearing from many is the the SS is hard as heck to get a double flare on. Are you guys using the stock brake stuff with the springy covering cut to your particular lengths? At this point you then establish your own flare at the cut end? Are you guys using the coil stuff and straightening it out then bending accordingly?

I would have liked to be able to use the 1/4 inch straight lengths of SS tubing but I guess the fittings would all have to be reduced for all the 3/16 brake fittings etc. Would that work?? Run it in SS 1/4 ..still looking at the flare task.
Lack of safety is definitely a thought in the single flare.

Thanks

Too bad we couldn't get away with compression fittings...LOL A nut and a ferrule would be so easy.
