There are a couple O-Rings that you need. One is on the outside of the center part that you turn that seals it to the chrome part. There is also an O-Ring that seals the chrome part to the inside of the hub. However, I recommend you take it apart and take it to an auto parts store and compare and try some O-Rings.

You can also check with LMC and see if they have a hub rebuild kit available.

Thirdly, you can reseal with silicone caulk on the outside of the chrome piece to the hub, but you still need a new O-Ring on the outside of the part you turn.
