    flare spanners?



    hi guys, just joined! searching high and low for refrigeration flare spanners from suppliers here in oz, but with no luck. had a few old boys tell me nobody makes them anymore, but find that hard to believe. the only type i can find are measured "across the flat" (ie. the gap in the jaws is 1/4", 3/8",1/2" etc and NOT for a 1/4", 3/8" or 1/2" flare nut!). even the torque wrench kits with interchangeable heads have changed to an "open end spanner" type... any thoughts?

    Yeah you have to add an extra 1/2" onto AF sizes to suit a flare nut if I remember correctly (maybe 1/4" or 3/8" ).
    I found the same problem as you when trying to buy some, oh well, they are at least handy for automotive brake lines, they are done up real tight and very easy to round .

    I don't think anyone uses flare spanners anymore to be honest. Flare's aren't really torqued up hard enough for rounding the nut to be an issue, better to have an open end torque wrench than a flare spanner that you can over tighten with.

    Here you could see what are "across flat" measurements spanners for common flare nuts:

    They are not as common now because the flare nuts are not a standard size, like they used to be.

    Flare spaners only work on the correct sized nut but different manufactures sell different sized nuts nowadays.

    Swedish BAHCO is a fine tools manufacturer.

    I have 4 adjustable wreches over 25 years up to 60mm.

    Better than any spanner.
