I would recommend not using an adhesive that will make the inlet impossible to remove. It's possible for the internal part to burn up from bad contacts, the same as the other end can, and it is easily replaced. I normally do not recommend silicone, but in this case it is the ideal sealant and can be easily refreshed if necessary, I ran a small bead around the outside edge and smoothed it with my fingertip.and a dab in the screw holes. It will seal fine, but will allow easy removal.
