I'm not so good with technical stuff, so I'll just write down what it says on the side of my bottle!:
0.625x18UNF TW B03765
PW310BAR PH465BAR 0.93KG 1.1L
ISO11119-2 USA/M0812 IA18 2010/07
TT0035 D TUV1
I'm guessing it was born July 2010?
That's all I can tell you about this one. I've used it once with the Invert Mini.
