Hi Glen. yes, the mouth of the groove is larger than the "O" ring. On mine,
which is taken directly from the Parker book, the groove is just under 1/16 inch
wider than the "O" ring rubber ( 1/4 inch round )
Of course, they measure it in thousandths and I don't have the info right
here but that's pretty close.
The depth of the groove is smaller than the "O" ring so a little rubber
sticks out.
The cross section of the groove measures enough square inches so that even
when the hatch is pushed down metal-to-metal there is still empty space in the
groove.
I could probably find the printed copy in my sub files but it's pretty
long. Best bet is to just download it from their site. It's free and is there so
people can design things using just the charts and different types of
applications that need "O" rings.
