Our records show this number replaced an older factory number, 99-1153, so if your parts book lists that number instead, it's the same washer under the earlier catalog numbering.
We don't have much more detail on this one beyond the description and the material. It's a small, inexpensive item worth keeping a couple of spares of, since a tired drain washer is a common source of a slow leak at a drain plug.
