anyway, in my working life, I actually met not one but
two people who would count the twists per inch
and the length of the rats tail.....both were un related to each other as far as I know.
Quite early in my career I discovered that left hand O2 unions were not an international standard. Especially as many airlines did not routinely service the O2 every night. Hence the dodgy set of various brass adapter couplings in the (Not to be shown to the CAA) cupboard at the far end of stores. We don't even have an O2 rig any more. The O2 qty is monitored and the bottle changed as required.
As for twists per inch, I am that man and I claim my prize.
But we digress....
