Hi Brian, there's no stupid questions mate....ask away!

Yes, they are some sort of fibre washers.

I have used O rings, and also cut some out of gasket material (from auto shops) and also used leather.

They are easy to make if you have some old leather from a belt or a pair of boots etc laying around the house.

If you use an O ring, use the tightest fitting one that you have.
