Copper Brake Line Nuts

  1. #1
    Just fitted a new axle and I'm now doing the brake lines.
    Came across this nut going into the box on the axle and its doesnt seem to be a standard size.

    Where can I get these and what are they called?

    The one on the left is a standard one and its the one on the right I'm after.

    the other and most common on the car are 10 x 1

    yes, ask a motor factor for them, ask for brake pipe unions though as they aren't bolts.larger one is 12mm,not as common as the 10mm but readily available
