I'm in awe of Klem's 2nd paragraph...

However, using a NPS thread - like on the through hull - in an NPT fitting - like on an unflanged seacock - only allows 3 turns. I know this because that is what the yard mechanics did with the sink through hull on my boat before I purchased the boat and fixed it.

Maine Sail has posted a good illustration of this problem here.
