Orange and black O ring the same?

[onebad7.3]

The original O ring on my LPOP was a square cut black one. The one I ordered online showed up, and its orange in color and doesn't seem to be the same thickness. Part number XC3Z-6619-AA is what I got. From what I found, it is the correct part number.
Anyone know anything about the two different O rings?
Thanks!

Orange one is fine. Used them plenty of times
