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.

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.
