antique diver wrote:Hi Mark, I just opened up a Sportsways 1/2" NPT threaded valve to check out the seat design. The USD seat has the same threads, and while the end holding the seat is smaller in diameter than the SW the diameter of the valve's volcano orifice fits into the USD seat tip just fine. I haven't tried it under pressure yet, but I don't see any reason it shouldn't work ok.

Bill, might just work. Can I get you to come over and block the manifold with your face while I pressure test it?

just kidding, I'll find a neighborhood kid to do it.

I'll have to take my seat out again. When I compared it to a USD seat the length and thread size looked different but it might just be my old man eyes. I'll look again. Thanks for the idea. Mark
