Disclaimer: I don't know ANYTHING about o-rings except what I googled yesterday.

In that googling, it appears that o-rings come in 'standard sizes'.

That does NOT mean that "our" o-ring has to be a standard size, but, if it "is" a standard size, then the closest SAE standard size "I" could find that corresponds to the measured cross section is "3.53 mm".
  • -226 50.390.46mm ID x 3.530.10mm cross section
  • nominal 2-1/4" OD, 2" ID, 1/8" cross section
There were no standard sizes (that I could find) that were 3.2mm.
