As others have said I found this came packaged with two different sized o-rings although this is not stated in the product description. So I paid for 2 o-rings but I can only use one making the price absurd for one thing and if you need two you're stuck because only one fits your model. Here is the packaging so you can see which o-ring fits which model. And they differ significantly in o-ring size between #1 and #2, so you can't even fit them with any of the other models. The best thing to do is run to the hardware store with the old one and pick it up.
