[PSUBS-MAILIST] gluing O-ring into grove?

[William Alford <walford@dbtech.net>]

I'm doing some pressure checks on a door seal mechanism. A large dia. o-ring
fits into a groove around the door entrance. It has been machined to correct
oring specs, but will not stay in the groove when door opens. I've not seen any
recommendations that o-rings may be glued in the groove since they are supposed
to be somewhat movable to seal against the groove/door junction. But since
these movements are quite small (mm), does anyone have experience with using a
flexible gasket material/glue to hold the o-ring into place?
