The o-rings are a critical part to prevent the props from unscrewing during flight. You would normally tighten the props until they hit the o-ring and then tighten another 3/4 turn or until they feel snug.
If they look worn, cracked or brittle they should be replaced. If you can't order them, you may find something in the same size at a hardware store.

You know this brain dead Navy veteran never uses them unless I'm flying with carbon fiber or a 2 blade after market set of props. It makes the the fit of the after market seat better on lock down. Looks like this pilot will be reevaluating how he uses the "O" rings when using factory props

If you can't find at hardware store(I could't find right size and hardness...critical) you get new orings with new blades. Expensive Oring, but cheaper than a new drone.
