Rob mate you might want to watch which one of those you use. If you look at them they all from the pictures appear to be different threads. So it will be a case of which one is right for where your putting it. Just a warning incase they are different and you fit the wrong one threading the fitting and turbo.
From a guess without measuring it i think the orange one looks similar to garrett oil fittings and is possibly 4AN by 1/8 NPT fitting but not sure i would just be carefull but the=n i may be completely wrong
