No idea but you might be able to find something really close at Lowes/Home Depot if you have the originals. They have a pretty fair assortment, last I checked.

Most likely, the ring width (cross-sectional diameter) is going to be a fractional size, 1/8", 3/16" or something like that, so you should be able to get a good idea just by feel. Then, just buy one or two based upon the approximate diameter of the old o-rings.

If you have the old assembly, you may be able to just try them out in the store.
