Deckel FP2 oil nipples - which thread?

Hi guys.

I am following Bruce's thread - and also others, that pop up because of his.

I happen to have the same problem, although I hope the damage is just a recent mistake.

Earlier I have looked at Ross's solution to the daily lubing, a one-shot oiler.

Now I have a used one-shot oiler, so I am looking at connectors and tubing.

(I am looking at Festo pneumatic connectors - can they be used for oil?)

But, not wanting to take my machine apart right now, I'll rather ask: Which thread
are the oil nippes on the left side of the vertical slide?

So I can have the parts waiting, when I decide to dismantle the machine.
Cheers
Erik
