Fx fill probe

It toke me some time to recognize the threads as well, usually I am ordering these things from aliexpress.

So far what I've got every extension line/tube, the male end is BSPP 1/8-28 and the female ends are either 10x1mm but mostly 1/8-28 NPT. But if you buy from EU most likely all will be BSPP.

Me to have my comfortable time with fittings I had to order taps in all 3 formats just to make sure I am not wasting time on wait...
