Beeswax or paraffin wax will be fine to seal the insert in with (the top part with the vent hole) so it can be undone easily when you want to remove it for cleaning and the wax can be melted again to reseal it with. On plastic instruments, use cork grease to avoid melting the plastic.

Some people may be against sealing the 8ve inserts in with anything, but it's always best to so there aren't any leaks as you can't guarantee an airtight seal with just metal-on-metal contact and the chances are they will leak, so it's always best to seal than not to seal.

The lower part (the well) that fits into the body should be glued in with shellac so it won't come undone easily (but it will come undone with heat if you have to remove it).

Don't apply the wax to the screw thread on the insert as it could run down and block off the vent hole (which you'll then have to unblock with a needle spring of around 0.7mm depending on the make). But apply the wax to the underside of the flange on the insert instead as it's flat and will seal against the top of the well - so heat the insert in a clean flame (from a gas torch or bunsen burner) and apply the wax to the underside of the flange and screw it back in place before the wax cools.

You can clean them in vinegar to remove oxides and mineral deposits, then wash and degrease them thoroughly before installing them.
