stainless hydraulic line flairing???

buddy of mine is trying to flare 1/2" stainless line for his suspension setup. He has all hydraulic fittings as well. the problem is when we get the line clamped into the flaring holder, put the flaring tool inside the hole to flare and twist down on it, the line just pushes through the other side of the flaring holder....is there a trick to it or maybe just the flaring holder sucks?? any help would be appreciated you hydraulic gurus!

If the split blocks are tightened all the way then your flare sucks.

Another thing to check is that your stainless is annealed. This is very important if your flaring and bending stainless. If it isn't, it will split at the flare and stress at the bends. I have read during WWII copper and stainless lines on airplanes would require annealing after a certain service hour. Due to the vibrations of the engine crackes would develop. To counter-act this, service men torched the flares to cherry red and let them cool without the aid of water. This annealed the metal so it wouldn't crack. Even for our military this was pretty ghetto, so buy the annealed now that it is commonly known, or chance annealing it yourself.

By the way, what wall tubing are you using? .035 is good for over 2000psi working pressure.

I had to buy a special flare tool for stainless line. The cone that flares the tube is not round, it is like a pentagon-cone shape.

For flaring hard or thick tube use a tool that rolls the flare out, not one that just tries to punch it straight. Ridgid and Rothenberger make nice ones.

hey did that to airplanes cause the metel would work harden. if you see a spool of copper in the bed of a truck that has been there forever it will be real stiff. its cause the vibrations and such made it work harden. that takes a long time to do though, years that is

i can atest to the copper i had a roll of 2" in the back of the company truck for ever and when i finnaly had to use it i could barely unroll it but when that shit is brand new its abotu 5 times easier to un roll

hmmm and to think people use copper for air lines?

t

i posted that to make people think about that befor they use copper. i dont think stainless would really do it, at least it would take a lot langer. as for the flaring problem, did you put any kind of lube on the flare? that would help a little. when i hardline the wagon im just gonna use parker compretion fittings
