Note to Moparts.com readers:
A friend of mine emailed me some actual design criteria for O-ring grooves. (Thank you)
My part is a little on the tight side for width, but it will be fine.
A more typical design would be 0.082" depth (vs my 0.089") and more room for the O-ring width 0.143" (vs my 0.105").
