I have a fuel tank roll-over valve and I'm trying to identify the thread. I believe it to be -6 JIC from a picture of a similar one, but I thought I could confirm if someone can tell me the diamater.

Any help appreciated.

Thanks

Think this might help Tim,

I dont think this was the table I used when making up hydraulic lines (was searching but couldnt find it) but I think the info on this one is correct.
