I'll look it up, but all ball valves have some sort of flat where the stem
penetration and packing adjustment is. If you've already changed to penetration
to a reach rod assembly, why not just set the valve further out on a small
bracket and stick a SS universal between them. I've turned assemblies like that
about a million times on Perry boats.

RE: [PSUBS-MAILIST] MBT Vents
Hi Vance,
I've got exactly that arrangement but am wanting larger
bore valves. D'you have any idea what that sort of valve George used is called?
They're not regular ball valves, they're a sort of ball valve in a hex shaped
body that has a flat surface to mate against the hull. I just don't know what
these things are called to go looking for them.
thanks,
Alec

George's favorite goop--RTV. You take the handle and follower off and run
the screws through the hull along with the shaft. Let it set, snug it up, stick
the handle back on and you've got a done deal. Sounds awful, but it worked
just fine and cost a grand total of about a dollar two-ninety-eight, plus
valve.
Vance

How is the valve handle sealed at the point where it penetrates the hull ?
I've seen both configurations but couldn't see how the handle penetration is
sealed.
