What's the thread o/d?
Plus that photo suggests 20tpi doesn't it?

Looks like a brake pipe nut - for 1/4 pipe could be 7/16x20 UNF or M12x1.

Please could you write down what makes you think that.
To my eyes, you are measuring five thread pitches over a distance of 1/4". That means 5 x 4 = 20 threads per inch.
You do not count the thread tips, just the gaps between the tips. Alternatively, if you do want to count the thread tips, you have to call the left hand one 'zero'.
I measure od as 0.465" or 11.83mm

1/20”, or 0.050” pitch equates to 1.27mm, so 20 tpi makes more sense.
Nearest inch size to 0.465” is 15/32, which sounds revolting. More likely fine M12x1.25.

You are correct
Losing the plot a little as pitch gauge suggested metricThis is where i was heading, but seems to head into uncommon sizing
Sort of, power steering rack transfer pipe as per my other thread

Volvo pas rack by any chance?
I used these,
I had to run a drill through them, thought it was because the pipe was slightly corroded but it might have been 1/4" tube?
If that was actually the case (and I had known I was going to have to drill them anyway) I would have bought the 3/16 version as they are cheaper..

Classic Saab 900.
You would think definitely metric then, but pipe is 1/4" and only reference found to the formed end is on Murican websites
Close. Saab
I think i will probably have to take a punt on that size and see if correct

If you are sure it's 1/4"
My metric pitch gauge is paired with whitworth, misplaced my unf/unc one......I think mrhaynes needs to get himself some examples of these different threads in both nut and bolt - but not cheap chinese junk that has a thread engagement of about 20%!
‘Go-no go’ gauges have been around for as long as testing has been.
Most certainly he would have (immediately) found that neither 1.0mm pitch or 24 tpi were appropriate.
Confusion has occurred due to the very metric swedes using, in this instance, less common fitting sizes and imperial pipe
Cheers.
Definite 1/4 pipe and roomy in the fitting, 6mm looks lost in it!
Will need to check insitu sizing as the originals, 12mm spanner, are bit restricted access

I've never seen any AN hardline fittings in that type.
What's on the other end? Might be easier to replace the whole line with a length of braided hose and pop AN fittings on both ends if it is something custom.
Might be worth trying to find a sabb parts catalogue and see if they list the thread in the parts description.

Having said that, an4 is a common size for clutch lines. Might be a bit small for pas
