what tool makes this tubing end flair thingy

Discussion in 'The Hokey Ass Message Board' started by 31Vicky with a hemi, Oct 21, 2011.

  1. Best that I can tell its formed. The inside of the tube follows the outside.
    This fitting is on just about every single GM or truck car manufactured over the last decade or two.

    If this is a one time deal can you splice on a JY end? Does NAPA or HELP! make a repair end?
     
  6. Not one a one time deal,
    Napa, Help, & Dorman do not have ends.

    FMSI makes all the fuel and trans line stubs.they also do nylon tubing fittings.
     
  8. Yes they handle lines with this end, "special flair" as they call it. thanks.
    Still looking for the tool to make it.
     
  9. Alrighty then , as stated in post # 28 I tried making these fit together. If you got it to work it must be way more involved than forming the end and cutting it down.
    First the opening needs to be slightly rolled over so that it slips past the oring.
    Next the taper leading up to the largest part of the formation needs to be there inorder to move the retaining clip. It's like pushing againts a brick wall.
    Next that taper limits the amount of inward travel as it does mate with the taper inside the fitting and the oring.

    Elpolacko, could you explain how you made this?

    Just screw the fitting out and get one that holds a flair or ferrule end. They put those on to facilitate quick factory ***embly. Get rid of them and you get rid of the problem.

    This is my thoughs, too.
    Is the other end of that fitting some kinda metric fitting? Or just straight machine thread (US)?
     
  12. There's no problem other than the the ***le's question.
    What tool makes this.

    There's more than one way around these fittings, that's not the problem.
     
  13. Ok found out some more info.
    The system was invented, produced, and supplied to GM by "Jiffy Tight"
    http://www.jiffy-***e.com/about.cfm

    "jiffy tight" does not manufacture the tube end, however, the two must work together. One is completely useless without the other.

    The tube end is formed by a three hit die process. First hit forms the flat raised ridge that contacts the retaining ring keeping the tube secure. This stretches the entire end of the tube to the diameter of the retaining surface.
    The second hit creates the 45* engaging slope that opens the retaining ring. This distorts the end of tube once again by closing it.
    The third hit reforms the end of the tube that seals against the oring. This final hit provides the uniformity to the tube.

    There are over 300 million of these ends put out in the road.

    Edit: just heard back from "mastercool" tech department, they currently do not have anything to create this particular tubing end. However its been in the R&D department for some time and they are working on it.

    The one trans I dealt with, I just shortened the extended part of the tube to the same length an snapped it in. Maybe I just got lucky, but it wasn't a big deal.

    At this point in the game, is it absolutely necessary to use this type of end. It seems like you could change the fitting in the trans and use a more standard tube end.
     
  15. yea changing the ends is an option but its not a onesy-twosy type of deal.
    I'm getting hammered with these things, 30 vehicles a year x 4 or 6 ends each.
    First its a wild goose Chase to find fittings because not all of the threads are the same even though the "Jiffy tight quick connection" end is identical.

    As it stands the easiest thing is the most expensive and biggest time delay and that is to order new lines from the dealer.

    New Fmsi tube ends with compression fittings.
    Junk yard ends with the same

    Last is compression fittings on rusted lines or Rubber hoses clamped on rusted lines if they aren't completely corrosion impaired.

    The proper solution would be to be able to make that end on demand in a few minutes.

    One last option, obviously not what you want but may be a bit cheaper than buying the tooling to make the bump. Have something like this CNC machined and sliver solder them on the ends of the tube.

  17. That's a really good idea, ill look into that for pricing.

    Mastercool makes the dies for the GM 3/8" Jiffy ***e transmission lines now. The newest universal hydracrimp flare tool set has spots in the molded case for the dies.
