trying to replace an old -222 o-ring, is this the 90 duro buna-n one with the right size?

For a dash size -222 in 90 durometer Buna-N, it matches the standard callout and the actual measured dimensions are 1.762 inch OD, 1.484 inch ID, and 0.139 inch width. It is also cross-referenced under part numbers like 568-222-90D and C1CE73.
