Default Fuel tubing flare tool

Hi all - QQ it seems like i'll need to flare some fuel lines in the AC (once the line has been pushed though the bushings) instead of creating them on a bench and then putting them in. I'm at the point where I need to get the tools to do this. I know there are a bunch (i've read all the posts). The "Rigid" bar style seems kinda big and i'm not sure that will work if I need to work between bulkheads etc. Does anyone have a recommendation for a flare tool specific to the needs of the 12Is?

Thatís the one I used and had to remove the handle to get to at least one of the tubes to flare on my iS. Something to consider when making your final selection.

Default Flare tool

+1 for the Rolo
I recall once or two instances where I cut and installed the tube and then bent it outward just enough to make the flare, then bent it back into position.
Itís not the tool for tight spaces, but it makes beautiful flares. No leaks!
2-cents,
Dave

I'm not an RV builder so I don't know exactly what you are doing, but couldn't you put the bushings on the tube, flare it on the bench and then install it? Or won't the bushings go through the hole.

Could save a lot of money on a tool, although I sure do like having new tools!

Just a thought...

I donít recall flaring in place being an issue. Most tubes were trial fit and bench flared before installing.

If you are building on an airport you may find a fellow builder that can lend you a flaring tool.

One helpful hint I picked up was putting a drop of oil on the tip of the flaring mandrel before doing the flare. It makes turning the lever easier and seems to yield a smoother sealing surface.

Default A little oil

Yes, a bit of oil worked well.
Also, the oil held bits of aluminum flakes that accumulate on the flare tip so you can wipe them off cleanly rather than them getting into the fuel line.
Suspect the flakes come from the ďwire edgeĒ made by the Tube cutter even though I deburred the inner edge some.
Anyway, use a drop of oil and wipe the tool clean between flares.
2-cents,
Dave

As others have mentioned, the Rolo-Flair tool is an excellent quality tool. It is a bit bulkier than some other options, but it definitely doable if you plan correctly.

Take for example the B and C tubes in the front of the fuselage. The Rolo-Flair can be used easily if the front is not yet clecoed on or the bottom skin is not yet clecoed on. The pictures below show the B and C tubes being flared in the fuselage by one of our customers. The tubes shown in this picture series are the premade CNC bent tubes. (B, C, E, F, G, H, J, and K)








In the aft end of the fuselage, there are no issues as the tubes can all be built and flared outside of the aircraft.



As for the A and D tubes...... someone who has built those will have to chime in as far as clearance on the tubes go for flaring.

The A & D tubes were those for which I had to remove the handle of the tool to flare them.
