i'm all ears...

the line OD is .4" (so ~ 10mm line). do you think I could put a standard flare on that line? the company that makes my flare kit (mastercool 71475, flare kit ) says it won't work. specifically, they said the 3/8" line flares would not work with my 10mm line. their kit will only put on a 10mm metric bubble flare, which i cannot find adaptors to AN.

are other flare kits able to work around this problem?
