Oversimplified?
Maybe I oversimplified. I bought both the thru-hull(straight threads) and the "seacock" at the same time. It looks like the one on the left in my previous post. I did notice the "NPT" but believe that is a typo. I have another one to install sitting on the boat and will check this weekend. I can tell you that the body screws all the way down onto the thru-hull. Well at least to the end of the threads in the body.The reason that I bought both the thru-hull and seacock as a package is due to size. On my H37C the engine and head thru-hulls are 3/4" and I could not find a "seacock" to fit. The new ones are bigger, 1 1/4" maybe? I know I have to fill the old hole and redrill to install.I also know about tapered versus straight threads. I have a ball valve on a thru-hull right now. If it is not REAL tight it leaks. And when you get it REAL tight the handle is likely to be where you cannot open and close it. But I have not had the problem of only getting three or four threads.
