Have you considered an o-ring groove in the plastic well? Hal, Have you considered an o-ring groove in the plastic well? Assuming greases won't affect your electronics, you could add a SMALL skin of grease to the o-ring to make it slide in easily. How about a tool that is just smaller than the bore that can push the o-ring into place? Just a couple of quick ideas.

We are using some small Orings in some of our assemblies, just to keep splashed water out, nothing really high pressure at all. We need to seat these Orings into a plastic well, which is slightly smaller than the uncompressed OD of the Oring. This is a bit of a hassle, especially on the products where there are 20 Orings. Has anyone developed any sort of a neat little compression and insertion tool for Orings? Any suggestions would be greatly appreciated!
