Help With Leak Test Results

Sheep castraters, eh? That's well outside my life's experience! What
would be a source of supply for such a thing?

Wings & Wheels doesn't appear to offer anything similar (
http://www.wingsandwheels.com/page23.htm ). I also checked
McMaster-Carr ( http://www.mcmaster.com/ ) by putting o-ring into the
find box at the upper left. It comes up with a page with mind-numbing
information - multiple shapes, multiple sizes, materials, hardness,
etc.

Can you offer any guidance, Ken?
