    Back in the olden days when I was a kid I was taught how to make a flare connection that would never leak.

    Old John taught me that you should never tighthen a flare nut with an open end or adjustable wrench. One should always use a FLARE NUT WRENCH to tighten a flare nut.

    The reason is that when you tighten a flare nut with an adjustable you are applying pressure only on 2 points at one time. With a flare nut wrench you are applying pressure on 6 points of the nut all at the same time. There is no chance of distorting the flare or the flare nut.

    So this has always been my practice until NOW! All of these ductless split systems are coming into this country from places as far away as Mars. On the 3/4 OD suction lines they put a metric gigantic flare nut. It would take a 36mm flare nut wrench to properly tighten this nut. Ain't nobody got no 36mm flare nut wrench

    The Sanyo rep. said, "Have you tried the internet?" Hmmm...geeez no wonder why I am a lowly contractor. I never thought of that!

    If anyone can suggest a supplier of a 36mm flare nut wrench please let me know. Yes, I did try the internet and every automotive and AC supplier.

    You know Ben you are the one, and reading your post, that got me bto buy my first set. We are doing a Mitsubishi job and I hadnt thought of that part yet.

    I think anything that big though it might be ok to use an adjustable.

    Hey Benny, you guys got a Snap On or Matco truck in your town. They would probably have a good one in the truck.





    Forget the Snop On guy. They don't show a 36mm flare wrench in their online catalog.

    They're also called crowfoot wrenches. The biggest I've seen is 21mm.

    And then there are flare nut wrenches that are not crow foot.

    You also got your pigeon toe and chicken leg wrenches.

    Oh Beencool, if you can build a duct tape blimp you can build a wrench. Go buy a 6 sided 36mm socket, 2 pieces of flat to make handles, and get the band saw and mig welder out.

    Beencool; Try scratching your arse while searching the internet, it works for me. Oh that is unless you bite your nails. I always use my 25 year old flare nut wrenches they never let me down. I think you'll be OK with an adjustable on those big flare nuts, keep your eyes closed if it really bothers you.

    OK, curiosity question, and I may be wrong, but

    You are talking the nuts on the condenser, right ?

    Are you using Sanyo's line sets or running your own ?
    If you are running your own, discard Sanyo's flare nuts and use standard nuts from the supply house. I think, but again do not quote me, that the nut thread is the same.

    I am going to look at one and check when I get back in the office on Monday and repost. Otherwise, post beforehand.

    Did you go to one of UR's factory service schools in New England ? Is that where they told you about this ?

    Again, Just curious...

    htg guy is the MAN! I just ordered one of these "Porche oil line wrenches". It's on the way.

    Now watch those Sanyo basstrads go to solder connections this year!. We always use soft tubing for the flare then we go to hard pipe. Never factory spaghetti tubing.
