    I am not sure if I have ever seen a left-right bushing. You can usually tell by looking at the threads which is the left hand side

    I have seen plenty of left-right couplings.

    The end that is left hand usually has a line or other marking on it

    Left and right bushing. They used to use them on radistor valves. I think the femsle side is the left hand but I haven’t worked on one in a long time.

    It depends on which side of the radiator your standing on.
