I've ran into this before too on a different duplicator. I ended up going to a tractor supply store and buying a decent sized, thick O-ring. Works pretty well in my case but they do crack and break after some time so you'll need to buy a few if you go this route. Also if you are really in a pinch you can use a bunch of rubber bands but that gets a little too "shade tree" for me.
