I'm not a fan of the o-rings because the cause the screw to sit a smidge high.

Believe it or now, I've had great results with PTFE tape (teflon tape, the stuff you use when attaching a showerhead).

This from an older post by Log Man:
The metric size 1.5mm X 3mm works a lot better. Available in Buna, Vitron, or Silicone.

McMaster-Carr

To view, click on metric, 1.5mm, 3mm, and view the material/quanity/price. Or check out the dash sizes and see just how inexpensive they really are.

LOG
I bought a 100 pack of what Log recommended a few years ago and have only gone through a couple. They last a long time even if you remove grip panels for frequent cleanings.

Also have some Challis from when I bought the bushings. They are good but seem a smidge less durable to me.

The Challis O-rings are thinner, and therefore less durable. But that thinness means that they don't cause the proud screw issue.

The #60 O-rings from Lowes are thicker, and more durable, but your screws won't sit flush. These ones are cheaper, and they can be bought over the counter.

Both work, so you just pick your poison.

Same with the metric size- they allow screws to sit flush
