Thanks @etpm!

I went through pipe thread misery earlier this year on some hydraulic fittings that just didn't match up with any of the standards known to me. I kept feeling like I couldn't use a thread gauge or micrometer properly. To save any of you similar misery, here is a helpful table that I found; (FWIW)

All the best,
