Why are you replacing the switch? They don't seem to go bad often so if you have a problem this probably won't correct it. In any case you don't have to remove the adapter fitting. You don't have to use anything on the switch but you can use thread-lock, thread sealer, or teflon tape. You will have to bleed the air out after you replace the switch. You can reuse the washer seal if you do remove the adapter. If you want you can smear a small amount of silicone on it but it should seal without it.
