I'll check.

I've had fairly good luck at Rona for O-rings. They USED to have a stash of different sizes.

There used to be a place called Able-O-Rings. Of course they don't exist anymore, but when I went looking for them I found this other place now, whose name I can't remember. But I can totally sort of remember how to get there. Wow, is this an incredibly helpful story.

Ok, in a pinch, a O-ring that is too big can be cut and superglued back together.

But I'll go check my jar of O rings for anything that might fit the bill.
