Thanks for the replies.

I got the Parker book and couldn't find the "style" that I want to
use: an O-ring in the bottom of a well, with a cylinder pressing on
it. As:

||_______||
|O_______O|

I thought that I had seen such a use, but maybe not.

Not that it matters, cause I don't really have any flexibility as far
as the sizes go. So, I'm going to make it and see what happens. I'll
let you know.

Can you machine a groove just over half the thickness (deep) of the
o-ring in the bottom of the well? Make it tight to retain the o-ring and
leave enough protruding to seal .
