Do I need to re-grease the o-rings when reusing them and how, with what?

O-rings do not have to be greased, if you purchased new o-rings we recommend wiping them down to remove any exes grease or residue that might be present from the manufacturing process.

Reused O-rings do not have to be regreased, we recommend rinsing them with distilled water and removing any residue that might be present before reusing them.
