A quality bronze thru-hull will last that long, which is why you do it right and never think about it again. There are low end versions that literally recommend inspection/replacement every 5 years.

Ok so I can put in 3/4 flush Buck Algonqin thru hulls, same tapered flange, just bigger hole. So that is what I am going to do, but... Now a question: I also came across 1/2 NPS thread tap. Wondering if tapping the NPT female side of a ball valve that is currently NPT would work? Would it allow more threads to contact? I am probably going to try it on an old gate valve that I can throw away when done. Just to see if it solves the old "cant mix nps with npt" problem. Anyone done this? Tap is about $24 bucks so this isnt a money saving route unless you could do 3 or 4.

Re: 1/2 inch sea cocks

I would not recut the threads. Just get the proper flanged adapter for the inside.
