Hello everyone! I'm re plumbing my project with 3/8 steel fuel lines but having a heck of a time double flaring. What is considered thin walled steel tubing? Mine is a coil, 3/8 o.d. (1/32 wall)? Tried double flaring it but just pushes through the tool as if the wall thickness is just too thick to conform. Anyone got any ideas?
It's not the tube, it's the clamp bar. You've got to have a good one. Heat treated and hardened bars that don't flex. I'll be you a dollar they are bent if you look close
Definitely not secure enough, all you need is a single bubble (Metric) flare for the hose clamp to sit behind, that will stop the hose from sliding off. Metric is first part of making a double flare, no need to turn it back on itself http://www.cunifer.com/
It should be double flared, if you need inverted flair. Metric bubbles have a different seat, A much simpler seat, easier to manufacture, easier to plumb and less leaky one too. But the entire fastening system is of a different design. If the clamp bar of your tool is bending (you should check that because it's real common with any tool that costs less than $90.00) it won't make any difference how tight the ends are. If it's like this () the tube slips. If the teeth aren't sharp the tube slips, if it's got the green coating on it you can catch an *** ache from that too. Inverted flair seat is first Iso bubble second.
